Check Digit Verification of cas no

The CAS Registry Mumber 1234342-09-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,3,4 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1234342-09:
(9*1)+(8*2)+(7*3)+(6*4)+(5*3)+(4*4)+(3*2)+(2*0)+(1*9)=116

Solid-phase synthesis of oligodeoxyribonucleotides without base protection utilizing o-selective reaction of oxazaphospholidine derivatives

Oka, Natsuhisa,Maizuru, Yukihiro,Shimizu, Mamoru,Wada, Takeshi

experimental part, p. 144 - 154 (2011/08/05)

A study on the development of a novel method to synthesize oligodeoxyribonucleotides without base protection is described. We found that nucleoside 3′-O-oxazaphospholidine derivatives exclusively react with the hydroxy group of nucleosides in the presence
