Check Digit Verification of cas no

The CAS Registry Mumber 1305319-03-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,5,3,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1305319-03:
(9*1)+(8*3)+(7*0)+(6*5)+(5*3)+(4*1)+(3*9)+(2*0)+(1*3)=112
112 % 10 = 2
So 1305319-03-2 is a valid CAS Registry Number.

A new and convenient approach for the preparation of β-cyanoethyl protected trinucleotide phosphoramidites

Janczyk, Matthaeus,Appel, Bettina,Springstubbe, Danilo,Fritz, Hans-Joachim,Mueller, Sabine

supporting information; experimental part, p. 1510 - 1513 (2012/03/22)

Herein we report a convenient approach for the preparation of fully protected trinucleotide synthons to be used for the synthesis of gene libraries. The trinucleotide synthons bear β-cyanoethyl groups at the phosphate residues, and thus can be used in standard oligonucleotide synthesis without additional steps for deprotection and work-up.
