124476-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124476-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,4,7 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124476-84:
(8*1)+(7*2)+(6*4)+(5*4)+(4*7)+(3*6)+(2*8)+(1*4)=132
132 % 10 = 2
So 124476-84-2 is a valid CAS Registry Number.

Synthesis and Reactions of 2-Amino-1-aryl-5-oxo-Δ2-pyrroline-3-carbonitriles
Schaefer, Harry,Gewald, Karl
, p. 315 - 322 (2007/10/02)
The reaction of malononitrile with α-chloro acetanilides 1 in presence of potassium carbonate yields the 1-aryl-5-oxo-Δ2-pyrrolin-3-carbonitriles 2, in presence of triethylamine the 4,6-diamino-1-aryl-2-oxo-2,3-dihydropyrrolopyridin-5-ca
