Check Digit Verification of cas no

The CAS Registry Mumber 225377-37-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,5,3,7 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 225377-37:
(8*2)+(7*2)+(6*5)+(5*3)+(4*7)+(3*7)+(2*3)+(1*7)=137
137 % 10 = 7
So 225377-37-7 is a valid CAS Registry Number.

Synthesis of phosphorodithioate DNA by the H-phosphonothioate method

Seeberger, Peter H.,Caruthers, Marvin H.,Bankaitis-Davis, Danute,Beaton, Graham

, p. 5759 - 5772 (2007/10/03)

A novel method for the efficient synthesis phosphorodithioate DNA using H-phosphonothioate synthons is described. The 5'-DMT-nucleotide H- phosphonothioate monomers were prepared in two high yielding steps, from commercially, available phosphoramidites. T
