Check Digit Verification of cas no

The CAS Registry Mumber 182747-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,7,4 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 182747-96:
(8*1)+(7*8)+(6*2)+(5*7)+(4*4)+(3*7)+(2*9)+(1*6)=172
172 % 10 = 2
So 182747-96-2 is a valid CAS Registry Number.

N3′→P5′ Oligodeoxyribonucleotide Phosphoramidates: A New Method of Synthesis Based on a Phosphoramidite Amine-Exchange Reaction

Nelson, Jeffrey S.,Fearon, Karen L.,Nguyen, Mark Q.,McCurdy, Sarah N.,Frediani, Jeff E.,Foy, Michael F.,Hirschbein, Bernard L.

, p. 7278 - 7287 (2007/10/03)

A new method for the synthesis of N3′→P5′ phosphoramidate oligodeoxynucleotides is demonstrated. Described herein is the synthesis of the monomers utilized in the phosphoramidite amine-exchange process and the experimental details pertaining to this new mode of chain assembly. The phosphoramidite amine-exchange method generates coupling yields in the 92-95% range per cycle and further enables the synthesis of chimeric phosphoramidate/phosphodiester or phosphoramidate/ phosphorothioate oligonucleotides with no instrument modifications.
