Check Digit Verification of cas no

The CAS Registry Mumber 1271239-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,1,2,3 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1271239-68:
(9*1)+(8*2)+(7*7)+(6*1)+(5*2)+(4*3)+(3*9)+(2*6)+(1*8)=149
149 % 10 = 9
So 1271239-68-9 is a valid CAS Registry Number.

The synthesis of piperidine nucleoside analogs - A comparison of several methods to access the introduction of nucleobases

Kova?ková, Soňa,Dra?ínsky, Martin,Rejman, Dominik

experimental part, p. 1485 - 1500 (2011/04/15)

This work deals with the synthesis of piperidine and hydroxypiperidine analogs of nucleosides. Starting from commercially available 3-hydroxypiperidine, proline or 4-hydroxyproline, a series of piperidine derivatives of both purine and pyrimidine nucleobases was prepared. Various methods of nucleobase attachment were evaluated. The prepared compounds were tested for cytostatic, antibacterial, and antiviral properties but no significant activity was found.
