Check Digit Verification of cas no

The CAS Registry Mumber 173205-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,2,0 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 173205-63:
(8*1)+(7*7)+(6*3)+(5*2)+(4*0)+(3*5)+(2*6)+(1*3)=115
115 % 10 = 5
So 173205-63-5 is a valid CAS Registry Number.

Microwave-assisted regioselective synthesis of acyclic nucleosides through an alkylating reaction with 2-oxa-1,4-butanediol diacetate

Qu, Guirong,Han, Suhui,Zhang, Zhiguang,Geng, Mingwei,Xue, Feng

, p. 819 - 824 (2006)

An efficient and green procedure for the synthesis of purine acyclic nucleosides through microwave-assisted, alkylation of various purine nucleobases with 2-oxa-1,4-butanediol diacetate in the absence of solvent and catalyst is described. The advantages of using this method include its environmental friendliness, simple manipulation, short reaction time, high regioselectivity, and good yields.
