Check Digit Verification of cas no

The CAS Registry Mumber 1246307-16-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,3,0 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1246307-16:
(9*1)+(8*2)+(7*4)+(6*6)+(5*3)+(4*0)+(3*7)+(2*1)+(1*6)=133
133 % 10 = 3
So 1246307-16-3 is a valid CAS Registry Number.

Synthesis of 8-bromo-N-benzylpurines via 8-lithiated purines: Scope and limitations

Gamadeku, Thywill,Gundersen, Lise-Lotte

experimental part, p. 2723 - 2735 (2010/11/03)

9-Benzylpurines have been lithiated in the 8-position and subsequently brominated when trapped with BrCCl2CCl2Br. The 8-bromopurines were isolated in excellent yields when the benzyl group carried an alkoxy or alkyl group in the ortho or para position. Without these substituents, the conversion was generally less, and formation of 8,8'-purinyl dimers was observed. There was also evidence of debenzylation in some instances. Bromination of 7-benzylpurines employing the same set of reaction conditions has also been achieved.
