Check Digit Verification of cas no

The CAS Registry Mumber 82091-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,9 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 82091-48:
(7*8)+(6*2)+(5*0)+(4*9)+(3*1)+(2*4)+(1*8)=123
123 % 10 = 3
So 82091-48-3 is a valid CAS Registry Number.

SYNTHESES AND HOMOPOLYMERIZATION OF 7,8-DIALKOXYCARBONYL-7,8-DICYANOQUINODIMETHANES

Iwatsuki, Shouji,Itoh, Takahito,Nishihara, Katsumi,Furuhashi, Hidehiko

, p. 517 - 520 (2007/10/02)

7,8-Dimethoxycarbonyl-7,8-dicyanoquinodimethane and 7,8-diethoxycarbonyl-7,8-dicyaniquinomethane were prepared succesfully as novel compounds.These two compounds homopolymerized readly under thermal, radical, and anionic conditions except for cationic one.Moreover, weak bases such as triethylamine, pyridine, and pyrrolidine were found to induce the homopolymerization.
