Check Digit Verification of cas no

The CAS Registry Mumber 119930-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119930-20:
(8*1)+(7*1)+(6*9)+(5*9)+(4*3)+(3*0)+(2*2)+(1*0)=130
130 % 10 = 0
So 119930-20-0 is a valid CAS Registry Number.

MECHANISTIC ASPECTS OF THE REACTION OF SOME PHOSPHONIUM YLIDES WITH ALKYL PROPYNOATES

Barluenga, Jose,Lopez, Fernando,Palacios, Francisco,Sanchez-Ferrando, Francisco

, p. 381 - 384 (1988)

The reaction of alkoxycarbonylmethylentriphenylphosphonium ylides 7 with alkyl propynoates 6 in dichloromethane proceeds via cycloaddition rather than Michael addition, to lead to stabilised phosphonium ylides.
