Yintoni inombolo yeCAS?

Inombolo ye-CAS (iNombolo yeNkonzo yee-Chemical Abstracts) lulandelelwano lwamanani olusetyenziselwa ukuchonga ngokukodwa i-chemical substance in the field of chemistry.Inombolo ye-CAS iqulethwe ngamacandelo amathathu ahlulwe yi-hyphen, umz. 58-08-2.Yinkqubo eqhelekileyo yokuchonga kunye nokwahlula izinto zeekhemikhali emhlabeni jikelele kwaye isetyenziswa ngokuqhelekileyo kwiinkalo zekhemikhali, isayensi kunye nesayensi. iikhemikhali, amayeza, isayensi yezinto kunye nezinye iinkalo. Inombolo ye-CAS ikuvumela ukuba ufumane ngokukhawuleza nangokuchanekileyo ulwazi olusisiseko, ifomyula yesakhiwo, iipropati zeekhemikhali kunye nezinye iinkcukacha ezihambelanayo zekhemikhali.

Kutheni kufuneka ndikhangele inombolo yeCAS?

Ukukhangela inombolo ye-CAS kuneenjongo ezininzi kunye nokusetyenziswa. Inokunceda izazinzulu, abaphandi kunye nabasebenzi bamashishini ukuba babone ngokukhawuleza ulwazi oluthile malunga nekhemikhali. Ukwazi inombolo ye-CAS yekhemikhali kubalulekile xa kusenziwa, uphando okanye ukuthengisa ikhemikhali, kunye nokukhangela inombolo ye-CAS kunokunceda ukuphepha ukusetyenziswa kakubi okanye ukudideka njengoko ezinye iikhemikhali zinokuba namagama afanayo okanye izifinyezo ngelixa inombolo ye-CAS iyingqayizivele.

Ndilwenza njani uphendlo lwenombolo yeCAS?

Kukho iindlela ezininzi kunye nezixhobo zokwenza uphendlo lwenombolo yeCAS. Enye indlela eqhelekileyo kukukhangela i-website ye-Chemical Abstracts Service (CAS), eyi-database esemthethweni yeenombolo ze-CAS kwaye inikezela ngolwazi olubanzi kwizinto zekhemikhali. Kukho nenani leewebhusayithi zomntu wesithathu kunye nezixhobo ezibonelela ngeenombolo ze-CAS zokujonga, ezihlala zibandakanya ulwazi oluninzi malunga nesicelo sekhemikhali, i-MSDS (i-Material Safety Data Sheets), kunye nezixhumanisi kwezinye imimiselo. Iinkampani okanye imibutho yophando inokusebenzisa ii-database zangaphakathi ukulawula nokubuza iinombolo ze-CAS kwiimfuno zabo ezithile.

Ukubaluleka kokuJonga inani leCAS kuShishino

Kwishishini lemichiza, ukujonga inombolo ye-CAS yinto ebalulekileyo kwaye ibalulekile. Ayincedi kuphela iinkampani ukuba ziqinisekise ukuba imichiza eziyisebenzisayo ithobela imigangatho nemimiselo yamazwe ngamazwe, ikwanciphisa nomngcipheko. Ngokomzekelo, xa ukhangela kumazwe ngamazwe, amanani e-CAS aqinisekisa ukuba iikhemikhali ezibonelelwa ngumthengisi zifana ncakasana nezo zifunwa licala lemfuno.Ukhangelo lweenombolo zeCAS luphinde ludlale indima ebalulekileyo ekuphuhliseni iikhemikhali ezintsha, ukuphicothwa kokuthotyelwa kwemveliso, kunye nolawulo lwempilo yendalo esingqongileyo kunye nokhuseleko.

Imingeni kunye nokuqwalaselwa kweNombolo ye-CAS yokuJonga

Nangona izixhobo zokujonga amanani e-CAS zifumaneka ngokubanzi, eminye imingeni ihleli. Ezinye iikhemikhali zingenakho inombolo ye-CAS eyabelwe yona, ngokukodwa izinto ezisandul 'ukuphuhliswa okanye ezidibeneyo, kwaye ukukhangela inombolo ye-CAS kunokuvelisa ulwazi olungahambelaniyo ngokuxhomekeke kumthombo wedatha. Ngoko ke, kubalulekile ukukhetha umthombo wedatha othembekileyo xa usenza umbuzo. Abanye oovimba beenkcukacha banokufuna umrhumo ohlawulweyo, ngoko ke abasebenzisi kufuneka balinganise ixabiso ledatha ngokuchasene neendleko zofikelelo.

Ukuqukumbela

Ukukhangela inombolo ye-CAS sisixhobo esiphambili kwishishini lemichiza, ukunceda onke amaqela ukuba aqinisekise ukhuseleko lwamachiza kunye nokuthotyelwa. Ukuqonda indlela yokwenza ngokufanelekileyo ukukhangela amanani e-CAS, kunye nokuqonda isicelo sabo kunye nemingeni kwishishini, kuya kuba luncedo olukhulu kwiingcali zeekhemikhali kunye neengcali ezinxulumene nazo. Ngokusebenzisa imithombo yedatha echanekileyo kunye nenegunya lokujonga inombolo ye-CAS, ukusebenza kakuhle kunye nokuthembeka kwedatha kunokuphuculwa ngokufanelekileyo.
