Check Digit Verification of cas no
The CAS Registry Mumber 170872-60-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,8,7 and 2 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 170872-60:
(8*1)+(7*7)+(6*0)+(5*8)+(4*7)+(3*2)+(2*6)+(1*0)=143
143 % 10 = 3
So 170872-60-3 is a valid CAS Registry Number.

A new approach to the synthesis of 2-aminopurine-2'-deoxyriboside via tri- n-butyltin hydride reduction
Schmidt,Cech
, p. 1445 - 1452 (1995)
A simple conversion of guanosine to 2-aminopurine-2'-deoxyriboside is described. Following the synthesis of the 2'-phenoxythiocarbonyl derivative of 6-chloroguanosine, 2-aminopurine-2'-deoxyriboside can be prepared by simultaneous reduction of both the 6-
