Check Digit Verification of cas no

The CAS Registry Mumber 124355-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,5 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124355-32:
(8*1)+(7*2)+(6*4)+(5*3)+(4*5)+(3*5)+(2*3)+(1*2)=104
104 % 10 = 4
So 124355-32-4 is a valid CAS Registry Number.

Synthesis and Antiviral Activity of 3'-Heterocyclic Substituted 3'-Deoxythymidines

Wigerinck, Piet,Aerschot, Arthur Van,Janssen, Gerard,Claes, Paul,Balzarini, Jan,et al.

, p. 868 - 873 (2007/10/02)

Various 3'-deoxythymidine analogues with an heterocyclic five-membered ring in the 3'-erythro position have been synthesized.The pyrrol-1-yl (3) and the 1,2,4-triazol-4-yl (5) compounds were synthesized from 1-(3-amino-2,3-dideoxy-β-D-erythro-pentofuranosyl)thymine.The pyrazol-1-yl (16a), imidazol-1-yl (16b), and 1,2,4-triazol-1-yl (16c) derivatives were obtained by epoxide opening of the corresponding 1-(2,3-anhydro-β-D-lyxofuranosyl)thymines followed by 2'-deoxygenation.Only the 3'-pyrrol-1-yl derivative showed marginal antiviral activity against human immunodeficiency virus.
