97132-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97132-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,3 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97132-35:
(7*9)+(6*7)+(5*1)+(4*3)+(3*2)+(2*3)+(1*5)=139
139 % 10 = 9
So 97132-35-9 is a valid CAS Registry Number.

Cyclization of N-Acylalanine and N-Acylglycine Esters
Schmierer, Roland,Mildenberger, Hilmar
, p. 1095 - 1098 (2007/10/02)
The cyclization of N-(2,6-Dialkylphenyl)-N-acylalanine and -glycine esters 1 to 2,4-pyrrolidinediones 2 or the enols 3 is described.The acylation of 3 gives O-acyl derivatives; the alkylation of 3 yields mixtures of O- and C-alkylation products.
