688038-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 688038-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,0,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 688038-53:
(8*6)+(7*8)+(6*8)+(5*0)+(4*3)+(3*8)+(2*5)+(1*3)=201
201 % 10 = 1
So 688038-53-1 is a valid CAS Registry Number.

Synthesis and structural study of pyrimidyl carbocyclic analogues of nucleosides based on cyclopentene rings
Teran,Gonzalez Moa,Mosquera,Santana
, p. 999 - 1002 (2001)
A series of 1,2-disubstituted carbonucleoside analogues of pyrimidine and 5-halopyrimidines with the unsaturated carbocycle cyclopentene was synthesized. AIM theory was applied to analyse the conformational and electronic effects of 5-halogenation.
