Check Digit Verification of cas no
The CAS Registry Mumber 2084-19-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2084-19:
(6*2)+(5*0)+(4*8)+(3*4)+(2*1)+(1*9)=67
67 % 10 = 7
So 2084-19-7 is a valid CAS Registry Number.

Method of making 2-thiols
-
Page/Page column 5, (2008/06/13)
A process for selectively making 2-thiols from alpha olefins is described. The process includes contacting a linear or branched alpha olefin having with H2S in the presence of a catalyst and recovering the 2-thiol from a product mixture. The catalyst includes a support and at least one metal selected from Group IIIA-VIIIA and the branched olefin is branched at the 3-position or higher with respect to the olefin double bond. Compositions wherein the 2-thiols are substantially free of 1 -thiol and 3-thiol isomers are also described.
