Check Digit Verification of cas no

The CAS Registry Mumber 892409-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,4,0 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 892409-81:
(8*8)+(7*9)+(6*2)+(5*4)+(4*0)+(3*9)+(2*8)+(1*1)=203
203 % 10 = 3
So 892409-81-3 is a valid CAS Registry Number.

Divergent synthesis and biological evaluation of carbocyclic α-, iso- and 3′-epi-nucleosides and their lipophilic nucleotide prodrugs

Ludek, Olaf R.,Kraemer, Tobias,Balzarini, Jan,Meier, Chris

, p. 1313 - 1324 (2007/10/03)

A new divergent approach towards carbocyclic α-, iso- and 3′-epi-nucleosides starting from enantiomerically pure (1S,2R)-2-benzyloxymethylcyclopent-3-enol (5) is described. In the key step, isomeric cyclopentanols were condensed with a N3-protected pyrimi
