106020-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106020-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,0,2 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 106020-50:
(8*1)+(7*0)+(6*6)+(5*0)+(4*2)+(3*0)+(2*5)+(1*0)=62
62 % 10 = 2
So 106020-50-2 is a valid CAS Registry Number.

Pyridines and 5H-Benzopyranopyridines Derived from Halochalcones
Latif, N.,Mishriky, N.,Haggag, B.,Basyouni, W.
, p. 1230 - 1234 (2007/10/02)
The halochalcones (1a-c) react with malononitrile in the presence of ammonium acetate to give the corresponding 2-amino-4,6-diaryl-3-cyano-pyridines (2a-c), whereas with ethyl cyanoacetate the 4,6-diaryl-3-cyano-2-pyridones (3a-c) are obtained.On the cont
