Check Digit Verification of cas no

The CAS Registry Mumber 1234312-39-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,3,1 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1234312-39:
(9*1)+(8*2)+(7*3)+(6*4)+(5*3)+(4*1)+(3*2)+(2*3)+(1*9)=110
110 % 10 = 0
So 1234312-39-0 is a valid CAS Registry Number.

Synthesis and properties of a novel type of acyclic nucleoside phosphonates: 2-(purin-9-yl)ethoxyphenylphosphonic acids

Hockova, Dana,Dracinsky, Martin,Holy, Antonin

experimental part, p. 2885 - 2892 (2010/08/05)

A series of novel acyclic nucleoside phosphonates with a built-in arylphosphonate moiety has been prepared by a microwave-assisted cross-coupling reaction as the key step. Their cytostatic and antiviral activities were tested. The pKa values of the target ortho-, meta- and para-substituted arylphosphonates were determined by 31P NMR titration studies.
