Check Digit Verification of cas no

The CAS Registry Mumber 903572-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,5,7 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 903572-34:
(8*9)+(7*0)+(6*3)+(5*5)+(4*7)+(3*2)+(2*3)+(1*4)=159
159 % 10 = 9
So 903572-34-9 is a valid CAS Registry Number.

New approach for the synthesis of 1-aryl- and 1-heteroaryl-5-nitrouracil derivatives

Gondela, Andrzej,Walczak, Krzysztof

, p. 2859 - 2864 (2007/10/03)

1-(2,4-Dinitrophenyl)-5-nitrouracil and its 3-methyl derivatives were synthesized and used as substrates in reaction with aromatic amines and amino pyridines. In the reaction of aniline with 1-(2,4-dinitrophenyl)-5-nitrouracil, only the acyclic adduct was isolated. When 1-(2,4-dinitrophenyl)-3-methyl-5-nitrouracil was treated with aniline and other aromatic amines or amino pyridines, the desired 1-aryl-5-nitrouracil derivatives were obtained in satisfactory yield. The influence of the free H-3 proton present in the uracil ring on the course of the reaction is discussed.
