Check Digit Verification of cas no

The CAS Registry Mumber 108895-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,9 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108895-40:
(8*1)+(7*0)+(6*8)+(5*8)+(4*9)+(3*5)+(2*4)+(1*0)=155
155 % 10 = 5
So 108895-40-5 is a valid CAS Registry Number.

3'-Substituted 2',3'-Dideoxynucleoside Analogues as Potential Anti-HIV (HTLV-III/LAV) Agents

Herdewijn, Piet,Balzarini, Jan,Clerq, Erik De,Pauwels, Rudi,Baba, Masanori,et al.

, p. 1270 - 1278 (2007/10/02)

A series of 2',3'-unsaturated and 3'-substituted 2',3'-dideoxynucleoside analogues of purines and pyrimidines have been synthesized and evaluated for their inhibitory activity against human immunodeficiency virus (HIV).The 2',3'-unsaturated analogues of 2',3'-dideoxycytidine (ddeCyd) and 2',3'-dideoxythymidine (ddeThd), 3'-azido-2',3'-dideoxythymidine (AzddThd), 3'-fluoro-2',3'-dideoxythymidine, 2',3'-dideoxycytidine (ddCyd), and 2',3'-dideoxyadenosine (ddAdo) emerged as the most potent inhibitors of HIV-induced cytopathogenicity in the human T lymphocyte cell lines ATH8 and MT4.In ATH8 cells ddCyd, ddeCyd, and ddAdo had the highest therapeutic index whereas in MT4 cells AzddThd, ddThd, ddCyd, and ddAdo were the most selective.Derivatives from ddThd in which the substituent group was linked to the 3'-carbon atom via a thio, sulfonyl, or oxygen bridge were far less inhibitory to HIV than was AzddThd.
