Check Digit Verification of cas no

The CAS Registry Mumber 87162-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,6 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87162-45:
(7*8)+(6*7)+(5*1)+(4*6)+(3*2)+(2*4)+(1*5)=146
146 % 10 = 6
So 87162-45-6 is a valid CAS Registry Number.

Syntheses of Hydroxymethyl-carotenoids Using Vinyl-Anions Generated by the Shapiro-Reaction

Buetikofer, Pierre-Andre,Eugster, Conrad Hans

, p. 1148 - 1174 (1983)

A versatile synthesis of hydroxymethyl-carotenoids with β- or ε-end groups is presented.It makes use of the reactive vinyl anions prepared by the Shapiro-reaction from (phenylsulfonyl)hydrazones of polyenones and their smooth 1,2-addition to polyenals.Thus, e.g. (3R,6'R)-β,ε-carotene-3,19-diol (72), an optically active model compound structurally very close to loroxanthin (1), has been sinthesized.
