Check Digit Verification of cas no

The CAS Registry Mumber 72304-17-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,0 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72304-17:
(7*7)+(6*2)+(5*3)+(4*0)+(3*4)+(2*1)+(1*7)=97
97 % 10 = 7
So 72304-17-7 is a valid CAS Registry Number.

SOLVOLYSIS OF SPIROOCTA-1,4,7-TRIEN-6-ONES EVIDENCE OF A VINYL CATION INTERMEDIATE

Ikeda, Toshihiko,Kobayashi, Shinjiro,Taniguchi, Hiroshi

, p. 387 - 390 (2007/10/02)

Ethanolysis of 1-aryl-5,7-di-t-butyl-2-phenylspiroocta-1,4,7-trien-6-one 2 proceeds via a vinyl cation generated by opening of the cyclopropene ring, judging from regiospecific ring opening and kinetics (ρ+= -3.0, m = 0.53, and rate dependence on pH of the solvent).
