Check Digit Verification of cas no

The CAS Registry Mumber 1452877-31-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,2,8,7 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1452877-31:
(9*1)+(8*4)+(7*5)+(6*2)+(5*8)+(4*7)+(3*7)+(2*3)+(1*1)=184
184 % 10 = 4
So 1452877-31-4 is a valid CAS Registry Number.

Synthesis of a new urea derivative: A dual-functional organocatalyst for Knoevenagel condensation in water

Le, Wen-Jun,Lu, Hong-Fei,Zhou, Jun-Tao,Cheng, He-Long,Gao, Yu-Hua

, p. 5370 - 5373 (2013)

A phenylalanine-urea compound-catalyzed Knoevenagel condensation in water is reported. Various aldehydes and active methylene compounds undergo condensation at room temperature to give the desired products in high yields. The mechanism of the condensation of aldehydes with Meldrum's acid catalyzed by the novel urea derivative is also disclosed.
