143996-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143996-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,9 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143996-80:
(8*1)+(7*4)+(6*3)+(5*9)+(4*9)+(3*6)+(2*8)+(1*0)=169
169 % 10 = 9
So 143996-80-9 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 (2007/10/02)
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
