Check Digit Verification of cas no

The CAS Registry Mumber 649719-86-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,1 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 649719-86:
(8*6)+(7*4)+(6*9)+(5*7)+(4*1)+(3*9)+(2*8)+(1*6)=218
218 % 10 = 8
So 649719-86-8 is a valid CAS Registry Number.

Synthesis of 2'-O,3'-O bicyclic adenosine analogues using ring closing metathesis

Busca, Patricia,Etheve-Quelquejeu, Melanie,Valery, Jean-Marc

, p. 9131 - 9134 (2007/10/03)

The synthesis of 2'-O,3'-O bicyclic adenosine derivatives is presented as the first examples of a new family of 13-membered ring bicyclic nucleoside analogues. Cyclisation was achieved through ring closing metathesis (RCM) on a diene intermediate using Grubbs' catalyst. The Z and E isomers were purified and characterised.
