208463-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 208463-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,6 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 208463-33:
(8*2)+(7*0)+(6*8)+(5*4)+(4*6)+(3*3)+(2*3)+(1*3)=126
126 % 10 = 6
So 208463-33-6 is a valid CAS Registry Number.

Functionalization of nucleoside analogs: Regiospecific conversion of 4'- hydroxyl groups to thioesters and deoxygenation of 3'-hydroxyl groups

Huang, Zhen,Benner, Steven A.

, p. 895 - 899 (1998)

Nucleoside analogs 3a-e were conveniently functionalized by regiospecifically converting 4'-hydroxyl groups to thioesters 4a-e (>90% yield) and reducing 3'-hydroxyl groups to give building blocks 2a-e in 85- 90% yields.
