134700-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134700-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134700-21:
(8*1)+(7*3)+(6*4)+(5*7)+(4*0)+(3*0)+(2*2)+(1*1)=93
93 % 10 = 3
So 134700-21-3 is a valid CAS Registry Number.

The synthesis and antiviral activity of some 4'-thio-2'-deoxy nucleoside analogues
Dyson,Coe,Walker
, p. 2782 - 2786 (2007/10/02)
Starting from benzyl 3,5-di-O-benzyl-2-deoxy-1,4-dithio-D-erythro-pentofuranoside (4), the following 2'-deoxy nucleoside analogues have been synthesized: 4'-thiothymidine (8), 3'-azido-4'-thio-deoxythymidine (10), and (E)-5-(2-bromovinyl)-4'-thio-2'-deoxy
