Check Digit Verification of cas no

The CAS Registry Mumber 1245817-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,8,1 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1245817-89:
(9*1)+(8*2)+(7*4)+(6*5)+(5*8)+(4*1)+(3*7)+(2*8)+(1*9)=173
173 % 10 = 3
So 1245817-89-3 is a valid CAS Registry Number.

Short synthesis of functionalized pentalongin derivatives using pyridinium ylid chemistry

Claes, Pieter,Jacobs, Jan,Claessens, Sven,De Kimpe, Norbert

experimental part, p. 7088 - 7096 (2010/10/01)

3-Substituted pentalongin derivatives possessing an acetal function at C-1 were synthesized by cyclization of acylmethylnaphthoquinones. The latter naphthoquinones were prepared starting from 2-dioxolanylnaphthoquinone by means of both a stoichiometric and a catalytic method deploying various pyridinium ylids.
