Check Digit Verification of cas no

The CAS Registry Mumber 118895-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,9 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118895-67:
(8*1)+(7*1)+(6*8)+(5*8)+(4*9)+(3*5)+(2*6)+(1*7)=173
173 % 10 = 3
So 118895-67-3 is a valid CAS Registry Number.

Zinc Chloride Catalyzed Rearrangements of 1,2-Dialkynyl-1,2-dihydroxy-3,6-dimethoxy-3,5-cyclohexadienes to Bicyclooctadienones and Bicyclooctadienones

Fernandez, Mario,Chang, Shoumo,Ziller, Joseph,Doedens, Robert J.,Moore, Harold W.

, p. 1379 - 1383 (2007/10/02)

Reported here are unusual rearrangements of 1 and 3 to the bicyclooctadienones 2 and 4.This was accomplished when a carbon tetrachloride solution of respectively 1 and 3 was refluxed for 2 h in the presence of zinc chloride.The structure and stereochemist
