Check Digit Verification of cas no

The CAS Registry Mumber 135645-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,4 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135645-62:
(8*1)+(7*3)+(6*5)+(5*6)+(4*4)+(3*5)+(2*6)+(1*2)=134
134 % 10 = 4
So 135645-62-4 is a valid CAS Registry Number.

Highly Regioselective Bromination Reactions of Polymethylpyrimidines

Strekowski, Lucjan,Wydra, Roman L.,Janda, Lubomir,Harden, Donald B.

, p. 5610 - 5614 (2007/10/02)

4,5-Dimethyl- and 4,5,6-trimethyl-substituted pyrimidines are brominated at C5-Me with NBS in CCl4 and at C4(6)-Me with bromine in acetic acid to give the corresponding bromomethyl derivatives in a high yield.The remaining methyl group(s) can also be brominated with high regioselectivity.The 2-methylthio substituent is not oxidized under these conditions.
