Check Digit Verification of cas no

The CAS Registry Mumber 690997-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,9,9 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 690997-48:
(8*6)+(7*9)+(6*0)+(5*9)+(4*9)+(3*7)+(2*4)+(1*8)=229
229 % 10 = 9
So 690997-48-9 is a valid CAS Registry Number.

Simple entry into isonucleosides: Synthesis of 6-amino-9-[(3S,4S,5R)-4- hydroxy-5-(hydroxymethyl)tetrahydrofuran-3-yl]purine

Mereyala, Hari Babu,Mamidyala, Sreeman Kumar

, p. 2965 - 2966 (2004)

A simple and efficient method for the preparation of isonucleoside 7 is described. The preparation of 1,4-anhydroxylitol 4, a key intermediate, is described by intramolecular cyclization of (2S,3R,4R)-3,5-dibenzyloxypentan-1,2, 4-triol 3 using diethyl car
