Check Digit Verification of cas no

The CAS Registry Mumber 1111149-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,1,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1111149-05:
(9*1)+(8*1)+(7*1)+(6*1)+(5*1)+(4*4)+(3*9)+(2*0)+(1*5)=83
83 % 10 = 3
So 1111149-05-3 is a valid CAS Registry Number.

Three-component reaction of triphenylphosphine, dimethyl acetylenedicarboxylate, and aldehyde benzoylhydrazones: An efficient one-pot synthesis of stable phosphorus ylides

Hassanabadi, Alireza,Anary-Abbasinejad, Mohammad,Dehghan, Alimohammad

experimental part, p. 132 - 138 (2009/04/06)

Protonation of the reactive 1:1 intermediate produced in the reaction between dimethyl acetylenedicarboxylate and triphenylphosphine by benzoylhydrazones leads to vinylphosphonium salts, which undergo Michael addition with the conjugate base of the NH aci
