181423-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181423-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,4,2 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 181423-22:
(8*1)+(7*8)+(6*1)+(5*4)+(4*2)+(3*3)+(2*2)+(1*2)=113
113 % 10 = 3
So 181423-22-3 is a valid CAS Registry Number.

Ribosylation of pyrimidine 2'-deoxynucleosides
Mikhailov, Sergey N.,De Clercq, Erik,Herdewijn, Piet
, p. 1323 - 1334 (1996)
The previously developed method for the preparation of 2'-O-D- ribofuranosyl-nucleosides is extended to ribosylation of 2'- deoxynucleosides. The scope and limitations of this reaction are discussed.
