215031-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215031-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,0,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 215031-98:
(8*2)+(7*1)+(6*5)+(5*0)+(4*3)+(3*1)+(2*9)+(1*8)=94
94 % 10 = 4
So 215031-98-4 is a valid CAS Registry Number.

Synthesis and antiviral studies of unsaturated analogues of isomeric dideoxynucleosides
Bera, Sanjib,Mickle, Travis,Nair, Vasu
, p. 2379 - 2395 (1999)
Novel isomeric dideoxynucleosides with unsaturation in the carbohydrate moiety have been synthesized. For example, isod4A was synthesized through a rearrangement reaction involving a cyclonucleoside. Support for the structures of both purine and pyrimidin
