Calculate Digit Verification of CAS Registry Number 157567-73:
(8*1)+(7*5)+(6*7)+(5*5)+(4*6)+(3*7)+(2*7)+(1*3)=172
172 % 10 = 2
So 157567-73-2 is a valid CAS Registry Number.

CHEMICAL SYNTHESIS OF DIMER RIBONUCLEOTIDES CONTAINING INTERNUCLEOTIDIC PHOSPHORODITHIOATE LINKAGES

Petersen, Kenneth H.,Nielsen, John

, p. 911 - 914 (2007/10/02)

Ribonucleosides, chlorobis(amino)phosphines and thiols react via phosphorothioamidites to form phosphorothioites.Oxidation with sulphur gives ribonucleoside phosphorodithioate triesters which after deprotection yields the phosphorodithioate ribonucleoside
