157163-04-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157163-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,6 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 157163-04:
(8*1)+(7*5)+(6*7)+(5*1)+(4*6)+(3*3)+(2*0)+(1*4)=127
127 % 10 = 7
So 157163-04-7 is a valid CAS Registry Number.

2-Oxoimidazolidine-4-carboxylate as a novel chiral auxiliary for kinetic resolution
Kubota, Hitoshi,Kubo, Akira,Nunami, Ken-Ichi
, p. 3107 - 3110 (1994)
A kinetic resolution by stereospecific amination using 2-oxoimidazolidine-4-carboxylate as a novel chiral auxiliary was investigated. The reaction of tert-butyl (4S)-1-methyl-3-(2-bromopropionyl)-2-oxoimidazolidine-4-carboxylate (5) with an equimolar benz
