Check Digit Verification of cas no

The CAS Registry Mumber 1025504-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,5,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1025504-52:
(9*1)+(8*0)+(7*2)+(6*5)+(5*5)+(4*0)+(3*4)+(2*5)+(1*2)=102
102 % 10 = 2
So 1025504-52-2 is a valid CAS Registry Number.

Synthesis, cytostatic and anti-HCV activity of 6-(N-substituted aminomethyl)-, 6-(O-substituted hydroxymethyl)- and 6-(S-substituted sulfanylmethyl)purine nucleosides

Silhar, Peter,Hocek, Michal,Pohl, Radek,Votruba, Ivan,Shih, I-hung,Mabery, Eric,Mackman, Richard

, p. 2329 - 2366 (2008/12/21)

An efficient and facile synthesis of a large series of diverse 6-(N-substituted aminomethyl)-, 6-(O-substituted hydroxymethyl)- and 6-(S-substituted sulfanylmethyl)purine nucleosides (55 examples of both ribo- and 2′-deoxyribonucleosides), aimed at identifying novel homologues of natural nucleosides, was developed. The key transformation involved nucleophilic substitutions of Tol-protected 6-(mesyloxymethyl)purine nucleosides by primary or secondary amines, alcoholates or thiolates. While the 2′-deoxyribonucleosides were inactive, the ribonucleosides exerted considerable cytostatic effects and some anti-HCV activity with low selectivity.
