Check Digit Verification of cas no

The CAS Registry Mumber 133697-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,9 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133697-40:
(8*1)+(7*3)+(6*3)+(5*6)+(4*9)+(3*7)+(2*4)+(1*0)=142
142 % 10 = 2
So 133697-40-2 is a valid CAS Registry Number.

Synthesis of 2',3'-Dideoxynucleosides from 5-Alkoxymethyluracils

Abdel-Megied, Ahmed E.-S.,Pedersen, Erik B.,Nielsen, Carsten M.

, p. 59 - 70 (2007/10/02)

A modified synthesis of protected 2,3-dideoxyribose 5 starting from L-glutamic acid (1) is described.Reaction of 5 with silylated 5-hydroxymethyluracil 7a and 5-alkoxymethyluracils 7b-e in the presence of trimethylsilyl triflate afforded an anomeric mixture of 2',3'-dideoxyuridine derivatives 8a-e and 9a-e.Deprotection with methanolic ammonia and separation by chromatography gave the corresponding nucleosides 10a-e and 11a-e.Treatment of 9b-e with tri(1H-1,2,4-triazol-1-yl)phosphine oxide and subsequent reaction of 12b-e with ammonia in dioxane afforded the cytosine derivatives 13b-e which on treatment with methanolic ammonia gave the corresponding 2',3'-dideoxycytidine derivatives 14b-e and 15b-e.In contrast with the parent compounds, these alkoxymethyl derivatives had no appreciable activity against human immunodeficiency virus (HIV-1).
