Check Digit Verification of cas no

The CAS Registry Mumber 154521-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,5,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 154521-76:
(8*1)+(7*5)+(6*4)+(5*5)+(4*2)+(3*1)+(2*7)+(1*6)=123
123 % 10 = 3
So 154521-76-3 is a valid CAS Registry Number.

4,4'-Dichloro- and 4-chloro-4'-hydroxy-2,2'-bis(trifluoromethyl)diphenyl sulphoxides and sulphones

Clark, James H.,Denness, James E.,Wynd, Andrew J.

, p. 249 - 252 (2007/10/02)

4,4'-Dichloro-2,2'-bis(trifluoromethyl)diphenyl sulphoxide can be prepared from 2-bromo-4-chlorobenzotrifluoride and converted to the 2,2'-bis(trifluoromethyl)diphenyl sulphone, although the oxidation is remarkably difficult owing to the steric protection
