Check Digit Verification of cas no

The CAS Registry Mumber 127572-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127572-50:
(8*1)+(7*2)+(6*7)+(5*5)+(4*7)+(3*2)+(2*5)+(1*0)=133
133 % 10 = 3
So 127572-50-3 is a valid CAS Registry Number.

Application of 2-Substituted Vinamidinium Salts to the Synthesis of 2,4-Disubstituted Pyrroles

Gupton, John T.,Krolikowski, Dale A.,Yu, Richard H.,Riesinger, Steve W.,Sikorski, James A.

, p. 4735 - 4740 (1990)

A variety of 2-substituted vinamidinium salts react with α-amino acid esters under basic conditions to produce 2-carbethoxy-4-substituted-pyrroles in good yield.The overall process represents a short and efficient synthesis of highly functionalized pyrrol
