Yintoni inombolo ye-CAS?
Inombolo ye-CAS, eyaziwa ngokuba yinombolo yenkonzo ye-Abststhys Into nganye eyaziwayo yamachiza, kubandakanya izinto, iikhomputha, imixube, kunye nee-biomolecules, zabelwe inombolo ethile ye-CAS. Le nkqubo yenombolo isetyenziswe ngokubanzi kwikhemikhali, amayeza, kunye nemizi-mveliso yesayensi yezixhobo kwaye yenzelwe ukubonelela ngomgangatho ongaguqukiyo wokuchonga izinto zekhemikhali.
Ulwakhiwo kunye nentsingiselo yenombolo ye-CAS
Inombolo ye-CAS inamanani amathathu kwifomathi "xxx-xx-x". Iinombolo ezintathu zokuqala zenombolo yesibini, amanani amabini aphakathi asetyenziselwa ukukhangela, kwaye idiji yendawo yokugqibela yidijithi yokutshekisha. Le nkqubo yenombolo yenzelwe ukuqinisekisa ukuba into nganye yekhemikhali inesazisi esahlukileyo, ukunqanda ukudideka ngenxa yokukhupha isifo okanye ulwimi. Umzekelo, inombolo ye-CAS yamanzi yi-7732-18-5, kwaye kubhekiswa kolu manqaku manani kwinto enye yekhemikhali ngaphandle kwelizwe okanye ishishini.
Ukubaluleka kwamanani e-CAS kunye neendawo zesicelo
Ukubaluleka kwenombolo ye-CAS kuboniswa ikakhulu kwezi zinto zilandelayo:

Ukuchongwa kwempahla yemichiza yehlabathi: Inombolo ye-CAS ibonelela ngesazisi esahlukileyo kwihlabathi jikelele. Nokuba kuncwadi lwesayensi, izicelo zechiza zepatent, iilebheli zemveliso okanye iifayile zedatha, inombolo ye-CAS isebenza njengomgangatho ofanayo kwaye iqinisekisa ulwazi olungaguqukiyo.

Ulawulo lwedatha kunye nokubuyiswa kwemali: Ngenxa yeentlobo ngeentlobo zeekhemikhali kunye nolwaziso lwazo oluntsonkothileyo, amanani e-CAS awenza ulawulo kunye nokubuyiswa kweenkcukacha zedatha yekhemikhali ngokufanelekileyo. Abaphandi, iinkampani zekhemikhali kunye neearhente zikarhulumente zinokukhawuleza kwaye zifikelele ngokuchanekileyo ulwazi malunga nezinto zekhemizili ngenombolo ye-CAS.

Ulawulo lomgaqo-nkqubo kunye nolawulo loKhuseleko: Kulawulo lweekhemikhali, iinombolo ze-CAS sisixhobo esibalulekileyo sokuqinisekisa ukuthotyelwa komgaqo. Imigaqo emininzi yesizwe neyengingqi, njengobhaliso, kuvavanyo, ugunyaziso kunye nothintelo lweekhemikhali (ukufikelela) kunye ne-Inotity Act (TSC), ifuna amanani e-CAS.

Ndiyifumana njani kwaye ndiyisebenzise njani inombolo ye-CAS?
Iinombolo ze-CAS zihlala zifumaneka ngogcino olukhethekileyo okanye uncwadi lweekhemikhali, ezinje ngeRegistry, i-Corkem, iChemspide, njl. Iinombolo ze-CAS zihlala zisetyenziswa kwiinkqubo zekhemikhali kunye neenkqubo zophando zokuthengwa, ukulawulwa komgangatho, kunye nokulungiselela kunye nolawulo lwamaphepha edatha enokhuseleko.
Isishwankathelo
Njengenkqubo yokuchonga iShemical Scals scocial Scocial Scocial Scocial Scocial Scoms, inombolo ye-CAS iphucula kakhulu ukusebenza kunye nokuchaneka kwemali yokufumana ulwazi lwekhemikhali. Iinombolo ze-CAS zidlala indima engenakufane kwishishini lekhemikhali, nokuba kuphando nangokukwemilo, okanye kumgaqo wokuthotyelwa kolawulo. Ke ngoko, ukuqonda kunye nokusebenzisa ngokuchanekileyo amanani e-CAS kubalulekile kubasebenzi becandelo lemichiza.
