Check Digit Verification of cas no

The CAS Registry Mumber 171284-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,2,8 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 171284-80:
(8*1)+(7*7)+(6*1)+(5*2)+(4*8)+(3*4)+(2*8)+(1*0)=133
133 % 10 = 3
So 171284-80-3 is a valid CAS Registry Number.

New solid phase synthesis of oligodeoxythymidine phosphorodithioates by a modified HObt-method

Eldrup, Anne B.,Felding, Jakob,Kehler, Jan,Dahl, Otto

, p. 6127 - 6130 (1995)

Two new dithiophosphorylating reagents 2a,b have been prepared and shown to give nucleoside monomers 3a,b with reactivities suitable for solid phase synthesis. An octamer and a nonamer deoxythymidine phosphorodithioate were prepared on a TentaGel support
