Check Digit Verification of cas no

The CAS Registry Mumber 2191-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2191-79:
(6*2)+(5*1)+(4*9)+(3*1)+(2*7)+(1*9)=79
79 % 10 = 9
So 2191-79-9 is a valid CAS Registry Number.

SYNTHESIS AND REACTIVITY OF DISULFONYL CHLORIDES FROM 1,1,1-TRICHLORO-2,2-BIS(4-CHLOROPHENYL)ETHANE

Novakovski, E.

, p. 1319 - 1322 (2007/10/02)

The corresponding disulfonyl chlorides, sodium disulfonates, and disulfonamides were obtained from 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane and its analogs by successive chlorosulfonation, hydrolysis, salting out, and ammonolysis.
