Check Digit Verification of cas no

The CAS Registry Mumber 1422064-26-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,0,6 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1422064-26:
(9*1)+(8*4)+(7*2)+(6*2)+(5*0)+(4*6)+(3*4)+(2*2)+(1*6)=113
113 % 10 = 3
So 1422064-26-3 is a valid CAS Registry Number.

Synthesis of new optically active 2-pyrrolidinones

Moutevelis-Minakakis, Panagiota,Papavassilopoulou, Eleni,Mavromoustakos, Thomas

, p. 50 - 73 (2013/03/14)

A new class of optically active 2-pyrrolidinones was synthesized, starting from S-pyroglutamic acid, a well known natural chiral synthon. The synthetic design followed led to the insertion of various substituents at positions 1 and 5 of the 2-pyrrolidinone ring, including the imidazole moiety. Some of them possess two or three stereogenic centers, the configuration of which was retained under the mild conditions used. The new compounds also carry an imidazole moiety, which, along with the 2-pyrrolidinone template, may prove pivotal to several biological processes.
