Check Digit Verification of cas no
The CAS Registry Mumber 139393-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,9 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139393-81:
(8*1)+(7*3)+(6*9)+(5*3)+(4*9)+(3*3)+(2*8)+(1*1)=160
160 % 10 = 0
So 139393-81-0 is a valid CAS Registry Number.

3-Methyl-5-nitropyrimidin-4(3H)-one reacts with ketones in the presence of ammonium salts to afford disubstituted pyrimidines and disubstituted 3-nitro-2-pyridones in a novel ring transformation reaction; nitropyrimidinone behaves as an activated diformylamine in the former case, and as a synthetic equivalent of α-nitroformylacetic acid in the latter case.
