Check Digit Verification of cas no

The CAS Registry Mumber 1427272-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,7 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1427272-52:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*7)+(3*2)+(2*5)+(1*2)=153
153 % 10 = 3
So 1427272-52-3 is a valid CAS Registry Number.

Synthetic strategies to 9-substituted 8-oxoadenines

Siah, Huey-San Melanie,Gundersen, Lise-Lotte

supporting information, p. 1469 - 1476 (2013/05/09)

Three synthetic routes to 9-substituted 8-oxoadenines have been studied: bromination of adenine followed by N-9-alkylation/arylation and finally hydrolysis; bromination of adenine, hydrolysis, and N-functionalization as the last step; and N-9-alkylation of adenine, halogenation, and finally hydrolysis. As long as the N-9-functional group is compatible with conditions required for introduction of the halogen, the latter strategy was the most efficient. Also, a strategy starting from 5-amino-4,6-dichloropyrimidine was found to be a very good alternative for synthesis of 9-substituted 8-oxoadenines.
