Check Digit Verification of cas no
The CAS Registry Mumber 145729-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,7,2 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145729-63:
(8*1)+(7*4)+(6*5)+(5*7)+(4*2)+(3*9)+(2*6)+(1*3)=151
151 % 10 = 1
So 145729-63-1 is a valid CAS Registry Number.

The facile synthesis of N(1),N(4)-dimethyl-5-substituted cytosines
Pluskota,Jankowski,Koroniak
, p. 2927 - 2934 (2007/10/02)
A facile, high yield synthesis of N(1),N(4)-dimethyl-5-alkyl (methyl, ethyl, n-propyl, n-butyl) cytosines has been described. This method seems to be an alternative and universal route to N(1),N(4)-methylated cytosines with any 5-substituent.
