Check Digit Verification of cas no

The CAS Registry Mumber 65645-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,4 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 65645-66:
(7*6)+(6*5)+(5*6)+(4*4)+(3*5)+(2*6)+(1*6)=151
151 % 10 = 1
So 65645-66-1 is a valid CAS Registry Number.

REACTION OF UNSYMMETRICAL N1,N4-DISUBSTITUTED 1,4-BENZOQUINONE DIIMINES WITH HYDROGEN CHLORIDE

Burmistrov, K. S.,Yurchenko, A. G.

, p. 1722 - 1724 (2007/10/02)

The point of entry of chlorine into the molecules of unsymmetrical p-benzoquinone imines in their reaction with hydrogen chloride is determined by the comparative stability of the isomeric quinonoid intermediates, which can be assessed by means of an addi
