903572-19-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 903572-19-0 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, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 903572-19:
(8*9)+(7*0)+(6*3)+(5*5)+(4*7)+(3*2)+(2*1)+(1*9)=160
160 % 10 = 0
So 903572-19-0 is a valid CAS Registry Number.

An efficient procedure for the synthesis of some N-nitroaryl derivatives of nucleobases via microwave-assisted N-nitroarylation of nucleobases in the presence of SiO2 and Cs2CO3 in DMSO, as the homogenizing solvent, is des

A convenient method for N-1 arylation of uracil derivatives

Gondela, Andrzej,Walczak, Krzysztof

, p. 4653 - 4657 (2007/10/03)

1-(4-Nitrophenyl)- and 1-(2,4-dinitrophenyl)uracil derivatives have been obtained by direct arylation of uracil and its 5-substituted derivatives using 1-fluoro-4-nitrobenzene or 1-fluoro-2,4-dinitrobenzene in the presence of a base. The application of the newly obtained uracil derivatives in further synthesis is also presented.
