Check Digit Verification of cas no

The CAS Registry Mumber 18392-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,9 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18392-59:
(7*1)+(6*8)+(5*3)+(4*9)+(3*2)+(2*5)+(1*9)=131
131 % 10 = 1
So 18392-59-1 is a valid CAS Registry Number.

Novel aromatic system, 2,3-diacetoxybenzocyclohepten-5-one

Peesapati, Venkateswarlu,Nagarapu, Lingaiah

, p. 962 - 965 (2007/10/02)

Reaction with lithium chloride in boiling dimethylformamide hes been shown to give high yields of 2,3-diacetoxybenzocyclohepten-5-one (4) from 2,3-diacetoxy-6,6-dibromo-6,7,8,9-tetrahydrobenzocyclohepten-5-one (3).Similar elimination occurs from 2,3-diacetoxy-6,9-dibromo-6,7,8,9-tetrahydrobenzocyclohepten-5-one (5) to give 4.
