Check Digit Verification of cas no
The CAS Registry Mumber 31172-01-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,7 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31172-01:
(7*3)+(6*1)+(5*1)+(4*7)+(3*2)+(2*0)+(1*1)=67
67 % 10 = 7
So 31172-01-7 is a valid CAS Registry Number.

A facile synthesis of acetyl alkyl disulfides
Freeman,Huang,Lin
, p. 699 - 700 (1994)
The preparation of acetyl alkyl disulfides 2, which are key intermediates for the synthesis of alkyl hydrodisulfides 1, from disulfides is described. Disulfides are oxidized to sulfinothioic acid S-esters (thiosulfinates) which thioalkylate thioacetic aci
