Yintoni iCAS?
I-CAS imele i-Chemical Abstracts Service, isiseko sedatha esigunyazisiweyo esekwe yi-American Chemical Society (ACS.) Inombolo ye-CAS, okanye inombolo yerejista ye-CAS, isazisi samanani esikhethekileyo esisetyenziselwa ukumaka izinto zekhemikhali, iikhompawundi, ukulandelelana kwezinto eziphilayo, iipolima, kunye nokunye. Kwishishini lemichiza, inombolo ye-CAS sisixhobo esibalulekileyo kuba inceda izazinzulu kunye neenjineli ngokulula nangokuchaneka ukuchonga nokubuyisela izinto ezithile zeekhemikhali.
Ukubaluleka kweNombolo yeCAS
Kwishishini lemichiza, ukuchongwa kunye nokulandelwa kwezinto zekhemikhali ngomnye wemiba ephambili yomsebenzi wemihla ngemihla. Njengoko imichiza inokuba namagama amaninzi, amagama aqhelekileyo okanye amagama eemveliso, oku kunokukhokelela ngokulula ekubhidekeni. inombolo yeCAS isombulula le ngxaki ngokubonelela ngenani elisemgangathweni elisetyenziswa kwihlabathi jikelele. Kungakhathaliseki ukuba utshintsho kwigama okanye ulwimi lwekhemikhali, inombolo ye-CAS ihlala ihambelana ngokukodwa nento ethile. Le ndlela ichanekileyo yokuchonga ibalulekile kwinani leenkalo ezibandakanya uphando kunye nophuhliso, ukuthenga, imveliso kunye nokuthotyelwa kwemithetho.
Ubume benombolo yeCAS kunye nokubaluleka kwayo
Inombolo ye-CAS idla ngokuba namacandelo amathathu: amanani amabini kunye nedijithi yokutshekisha. Ngokomzekelo, inombolo ye-CAS yamanzi yi-7732-18-5. Esi sakhiwo, nangona sibonakala silula, sithwala ulwazi oluninzi. Amanani amathathu okuqala amele indawo ye-substance kwi-Chemical Abstracts Service, iseti yesibini yamanani ibonisa iimpawu zento eyodwa, kwaye idijithi yokutshekisha yokugqibela isetyenziselwa ukuqinisekisa ukuba amanani angaphambili achanekile. Ukuqonda isakhiwo samanani e-CAS kunceda iingcali ukuba ziqonde ngokukhawuleza kwaye zizisebenzise.
I-CAS kuShishino lweMichiza
Amanani e-CAS asetyenziswa ngokubanzi ekubhaliseni, ekulawuleni nasekurhwebeni kweemveliso zeekhemikhali. Ngexesha lokubhaliswa kunye nokungeniswa kweemveliso zeekhemikhali, iinombolo ze-CAS zihlala zifunwa ngamaqumrhu alawulayo ukuqinisekisa ukhuseleko kunye nokusemthethweni kweekhemikhali. Kurhwebo lwamazwe ngamazwe, iinombolo zeCAS zikwasetyenziselwa ukuqinisekisa ukuba abathengi kunye nabathengisi banolwazi olufanayo lwemveliso ethengiswayo. Abaphandi bemichiza nabo kufuneka bacaphule amanani e-CAS xa bepapasha uncwadi okanye befaka isicelo samalungelo awodwa omenzi wechiza ukuqinisekisa ukuchaneka kunye nokuqinisekiswa kweziphumo zabo.
Indlela yokusebenzisa amanani eCAS ukufumana ulwazi
Ukusebenzisa iinombolo ze-CAS, abasebenzi bezoshishino beekhemikhali banokufumana ngokuchanekileyo ulwazi malunga neekhemikhali kwiinkcukacha ezininzi. Ngokomzekelo, ulwazi malunga nePhepha leDatha loKhuseleko lwekhemikhali (SDS), ubuthi, impembelelo yokusingqongileyo, indlela yokuvelisa kunye nexabiso lemarike inokufumaneka ngokukhawuleza usebenzisa inombolo ye-CAS. Lo buchule bokukwazi ukubuyiswa bunexabiso elikhulu kwiinkampani ekwenzeni izigqibo ze-R&D kunye novavanyo lomngcipheko.
Ukuthelekiswa kwamanani e-CAS kunye nezinye iisistim zamanani
Nangona amanani e-CAS esetyenziswa kakhulu kwishishini lemichiza, ezinye iinkqubo zokubala zikwakhona, njengenombolo ye-UN yeZizwe eziManyeneyo okanye inombolo ye-EINECS ye-European Union. Xa kuthelekiswa, amanani e-CAS anokufikelela ngokubanzi kunye nokuchaneka okuphezulu. Oku kukhokelele ekulawuleni kwamanani e-CAS kwishishini lemichiza kwinqanaba lehlabathi.
Ukuqukumbela
I-CAS, njengesichongi esisemgangathweni sezinto zekhemikhali, ibe sisixhobo esiyimfuneko kwishishini lemichiza. Ngokusebenzisa amanani e-CAS, iinkampani zeekhemikhali kunye nabaphandi bayakwazi ukulawula nokusebenzisa ulwazi lwemichiza ngokuchanekileyo nangokufanelekileyo, ngaloo ndlela bekhuthaza uphuhliso lweshishini kunye nokuqhubela phambili kwezobuchwepheshe. Ukuqonda kunye nokusetyenziswa ngokuchanekileyo kwenombolo ye-CAS ayikwazi nje ukuphucula ukusebenza kakuhle, kodwa kwakhona ukuphepha ngokufanelekileyo ingozi enokwenzeka.
