Check Digit Verification of cas no

The CAS Registry Mumber 321961-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,9,6 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 321961-56:
(8*3)+(7*2)+(6*1)+(5*9)+(4*6)+(3*1)+(2*5)+(1*6)=132
132 % 10 = 2
So 321961-56-2 is a valid CAS Registry Number.

Avdeenko,Konovalova,Ludchenko,Ledeneva,Vakulenko

experimental part, p. 214 - 229 (2011/05/05)

New N-acetyl-1,4-benzoquinone monoimines alkyl-substituted in the quinoid ring were synthesized. The hydrohalogenation of N-acetyl(aroyl)-1,4-benzoquinone monoimines proceeds exclusively in keeping with the 1,4-addition. The hydrochlorination occurs along the ionic mechanism, in the hydrobromination grows the role of the radical mechanism.
