Check Digit Verification of cas no

The CAS Registry Mumber 217798-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,7,9 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 217798-89:
(8*2)+(7*1)+(6*7)+(5*7)+(4*9)+(3*8)+(2*8)+(1*9)=185
185 % 10 = 5
So 217798-89-5 is a valid CAS Registry Number.

Synthesis of organoselenium sulfonamides as new potential cytokine inducers: 2,2'-Diselenobis(benzenesulfonamides) and 1,3,2- benzothiaselenazolone 1,1-dioxides

Kloc, Krystian,Mlochowski, Jacek

, p. 67 - 71 (1999)

A convenient method for the synthesis of 2,2'- diselenobis(benzenesulfonamides) 4 and 2-substituted 1,3,2- benzothiaselenazole 1,1-dioxides 2, has been elaborated. It is based on the conversion of 2-aminobenzenesulfonic acid into bis[2-(chlorosulfonyl)phe
