Check Digit Verification of cas no

The CAS Registry Mumber 215445-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,4,4 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 215445-56:
(8*2)+(7*1)+(6*5)+(5*4)+(4*4)+(3*5)+(2*5)+(1*6)=120
120 % 10 = 0
So 215445-56-0 is a valid CAS Registry Number.

Synthesis of 3'-C-branched 1',5'-anhydromannitol nucleosides as new antiherpes agents

Hossain, Nafizal,Van Halbeek, Herman,De Clercq, Erik,Herdewijn, Piet

, p. 2209 - 2226 (1998)

A series of 3'-β-C-branched anhydromannitol nucleosides were conveniently synthesized starting from commercially available D-ribose. The reaction sequences were: (i) conversion of the protected pentofluranose to the corresponding nitrohexopyranose; (ii) addition of the conjugated base of the nitrosugar to formaldehyde; (iii) removal of the nitro group by n-tributyltin hydride treatment and (iv) Mitsunobu type alkylation to introduce the nucleobase. The conformation of intermediates and final compounds were deduced from NMR analysis. The thymine congener showed potent activity against herpes simplex virus (HSV).
