Check Digit Verification of cas no

The CAS Registry Mumber 276870-78-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,6,8,7 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 276870-78:
(8*2)+(7*7)+(6*6)+(5*8)+(4*7)+(3*0)+(2*7)+(1*8)=191
191 % 10 = 1
So 276870-78-1 is a valid CAS Registry Number.

Diastereoselective synthesis of α-substituted-γ-butyrolactones of nucleosides via [1,5]-c,h insertion reactions of α-diazomalonates of nucleosides

Lim, Jinsoo,Choo, Dong-Joon,Kim, Yong Hae

, p. 553 - 554 (2007/10/03)

Diastereoselective and regioselective [1,5]-C,H insertion reactions of 2'-deoxy-3'-diazomalonate nucleosides afforded τ-butyrolactones of nucleosides as chiral synthons for the preparation of 2'-C-branched nucleosides.
