Check Digit Verification of cas no

The CAS Registry Mumber 3950-63-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3950-63:
(6*3)+(5*9)+(4*5)+(3*0)+(2*6)+(1*3)=98
98 % 10 = 8
So 3950-63-8 is a valid CAS Registry Number.

A New Group of Compounds Derived from Nereistoxin - Synthesis of Bis-dimethylamino-tris-disulfanes

Muehlstaedt, M.,Heinicke, J.,Schubert H.

, p. 841 - 847 (2007/10/02)

The reaction of organo-thiosulfates, BUNTE-salts, with mercaptans is a convenient synthesis of disulfanes.Similarly bis-BUNTE-salt 7 and tert. butyl mercaptan give bis-disulfane 5c.By treating 7 with several aliphatic mercaptans we found the formation of the tris-disulfanes 8a-d in preparative amounts in addition to the bis-disulfanes 5a-d expected.This reaction was investigated.The preparation of the compounds 8 is described and a proposal is given for a mechanism of the formation of 8 as a thiol-disulfide-interchange.
