Check Digit Verification of cas no

The CAS Registry Mumber 199170-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199170-77:
(8*1)+(7*9)+(6*9)+(5*1)+(4*7)+(3*0)+(2*7)+(1*7)=179
179 % 10 = 9
So 199170-77-9 is a valid CAS Registry Number.

Addition of nucleophiles to 6-vinylpurines

veras, Anniken T.,Bakkestuen, Anne Kristin,Gundersen, Lise-Lotte,Rise, Frode

, p. 1116 - 1124 (2007/10/03)

6-Vinylpurines readily participate in nucleophilic addition reactions. Treatment with sodium salts of alcohols and thiols, as well as stabilised carbanions, results in clean conversion into a variety of functionalized purine derivatives. Additions performed in the presence of acid give 1:1 adducts together with dimeric purine products. Under acidic conditions the adduct first formed reacts further with another molecule of vinylpurine. Acta Chemica Scandinavica 1997.
