Check Digit Verification of cas no

The CAS Registry Mumber 1065646-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,5,6,4 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1065646-52:
(9*1)+(8*0)+(7*6)+(6*5)+(5*6)+(4*4)+(3*6)+(2*5)+(1*2)=157
157 % 10 = 7
So 1065646-52-7 is a valid CAS Registry Number.

Intramolecular aza-anti-Michael addition of an amide anion to enones: A regiospecific approach to tetramic acid derivatives

Bi, Xihe,Zhang, Jingping,Liu, Qun,Tan, Jing,Li, Bing

, p. 2301 - 2306 (2007)

A novel intramolecular aza-anti-Michael addition was disclosed in the one-pot reactions between 3-oxobutanamides and aryl (heteroaryl) aldehydes under basic conditions, in which amide anions regiospecifically attacked the ct-carbon of an enone fragment, p
