Check Digit Verification of cas no
The CAS Registry Mumber 1191-67-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,9 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1191-67:
(6*1)+(5*1)+(4*9)+(3*1)+(2*6)+(1*7)=69
69 % 10 = 9
So 1191-67-9 is a valid CAS Registry Number.

Process for preparation of dithiols
-
, (2008/06/13)
The invention relates to the synthesis of dithiols and more particularly that of α,ω-dithiols having 5 to 20 carbon atoms. The process according to the invention comprises reacting a di-(tertiary-alkylthio)alkane with hydrogen sulphide in the presence of a solid acid catalyst. The alkane dithiol is obtained selectively and a tertiary-alkyl mercaptan is obtained as by-product. It is possible to reuse the latter in a cyclical process to produce the original di-(tertiary-alkylthio)alkane.
