Check Digit Verification of cas no
The CAS Registry Mumber 138395-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,9 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138395-59:
(8*1)+(7*3)+(6*8)+(5*3)+(4*9)+(3*5)+(2*5)+(1*9)=162
162 % 10 = 2
So 138395-59-2 is a valid CAS Registry Number.

A useful methodology for the regioselective deprotection of 1,3-dibenzyluracils
Botta,Summa,Saladino,Nicoletti
, p. 2181 - 2187 (1991)
A practical, regioselective N-1 deprotection of 1,3-dibenzyl uracils 2 a-e is described. The same experimental procedure and longer reaction time afforded the complete deprotection of the uracils.
