Check Digit Verification of cas no

The CAS Registry Mumber 823-66-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 823-66:
(5*8)+(4*2)+(3*3)+(2*6)+(1*6)=75
75 % 10 = 5
So 823-66-5 is a valid CAS Registry Number.

THE MEYER-SCHUSTER REACTION FOR TERTIARY ACETYLENIC ALCOHOLS WITH CYCLOPROPYL SUBSTITUENTS

Sakharov, B. N.,Lipkin, M. A.,Markevich, V. S.

, p. 714 - 717 (2007/10/02)

In the case of 2-cyclopropyl-3-pentyn-2-ol and 1,1-dicyclopropyl-2-butyn-1-ol it was shown for the first time that tertiary acetylenic alcohols with cyclopropyl substituents rearrange to the corresponding α,β-unsaturated ketones in the Meyer-Schuster reaction.
