Check Digit Verification of cas no

The CAS Registry Mumber 262430-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,2,4,3 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 262430-01:
(8*2)+(7*6)+(6*2)+(5*4)+(4*3)+(3*0)+(2*0)+(1*1)=103
103 % 10 = 3
So 262430-01-3 is a valid CAS Registry Number.

Investigation of a facile synthetic method for phosphorothioate dimer synthons in oligonucleotide phosphorothioates synthesis

Miyashita, Takanori,Yamada, Kohei,Kondo, Kazuhiko,Mori, Kenya,Shinozuka, Kazuo

, p. 955 - 962 (2007/10/03)

A facile synthetic method of a phosphorothioate dimer block was investigated. Dinucleoside phosphite triester intermediates were obtained in one-pot synthesis by the coupling of a protected nucleoside bearing free 5'- OH and a protected nucleoside bearing free 3'-OH in the presence of phosphorous trichloride (PCl3) and 1,2,4-triazole. The intermediates were easily sulfurized to afford the desired phosphorothioate dimer blocks in 33- 64% overall yields.
