Check Digit Verification of cas no
The CAS Registry Mumber 211510-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,5,1 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 211510-45:
(8*2)+(7*1)+(6*1)+(5*5)+(4*1)+(3*0)+(2*4)+(1*5)=71
71 % 10 = 1
So 211510-45-1 is a valid CAS Registry Number.

C-5 Modified nucleosides: Direct insertion of alkynyl-thio functionality in pyrimidines
Held, Heike A.,Roychowdhury, Abhijit,Benner, Steven A.
, p. 391 - 404 (2003)
A route is presented to append, in a single step, alkynyl thioesters to the 5-position of a pyrimidine ring of a nucleoside that is unprotected. These products should be useful to support in vitro selection experiments with functionalized DNA.
