Check Digit Verification of cas no

The CAS Registry Mumber 290293-15-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,2,9 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 290293-15:
(8*2)+(7*9)+(6*0)+(5*2)+(4*9)+(3*3)+(2*1)+(1*5)=141
141 % 10 = 1
So 290293-15-1 is a valid CAS Registry Number.

Diastereoselective and enantioselective synthesis of 4'-aza analogues of 2',3'-dideoxynucleosides

Chiacchio, Ugo,Rescifina, Antonio,Corsaro, Antonio,Pistara, Venerando,Romeo, Giovanni,Romeo, Roberto

, p. 2045 - 2048 (2000)

A diastereo- and enantioselective synthesis of 4'-aza analogues of 2',3'-dideoxynucleosides has been designed by the strategy of the 1,3-dipolar cycloaddition reaction of a Vasella-type nitrone. The reaction leads to (1'R)- and (1'S)-4'-aza analogues of 2',3'-dideoxythimidine and fluorouridine, in enantiomerically pure forms. Copyright (C) 2000 Elsevier Science Ltd.
