Check Digit Verification of cas no

The CAS Registry Mumber 50993-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,9 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 50993-74:
(7*5)+(6*0)+(5*9)+(4*9)+(3*3)+(2*7)+(1*4)=143
143 % 10 = 3
So 50993-74-3 is a valid CAS Registry Number.

Reaction of 3-oxo-3-R1-N-R2-propanethioamides with 2-amino-5-R-pyridines

Britsun,Borisevich,Pirozhenko,Lozinskii

, p. 276 - 279 (2007)

Direction of a reaction between 3-oxo-3-R1-N-R 2-propanethioamides and 2-amino-5-R-pyridines in acetic acid depends on the structure of initial thioamides: at R1 = Me, R2 = Ar, Et 2-methyl-7-R-4H-pyrido[1,2-a]-p

General trends in reaction of N-aryl-3-oxobutanethioamides with 2-aminoazoles(azines)

Britsun,Borisevich,Lozinskii

, p. 1548 - 1552 (2008/09/16)

Reaction products obtained from N-aryl-3-oxobutanethioamides and 2-aminoazoles(azines) are derivatives of (arylamino)pyrimidines and pyrimidinethiones. The ratio of the products depends on the basicity of 1,3-binucleophiles, acidity of the medium, and the character of substituents in the phenyl ring of initial thioamides.
