77643-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77643-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,4 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77643-65:
(7*7)+(6*7)+(5*6)+(4*4)+(3*3)+(2*6)+(1*5)=163
163 % 10 = 3
So 77643-65-3 is a valid CAS Registry Number.

Addition de cyano-2 aziridines a quelques alcynes; obtention de pyrroles
Merah, Boumediene,Texier, Fernand
, p. 552 - 558 (2007/10/02)
Addition of the α-bromocinnamonitrile to primary amines (Cromwell method) leads to 2-cyano-3-phenyl-N-alkyl-aziridines, but the formation of the isomeric enamines always competes with this reaction.These aziridines, which are potential azomethine-ylids, a
