Check Digit Verification of cas no

The CAS Registry Mumber 78272-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78272-45:
(7*7)+(6*8)+(5*2)+(4*7)+(3*2)+(2*4)+(1*5)=154
154 % 10 = 4
So 78272-45-4 is a valid CAS Registry Number.

NOUVELLE SYNTHESE SIMPLE DE NUCLEOSIDE PHOSPHOROTHIOLATE

Asseline, U.,Thuong, N. T.

, p. 847 - 850 (2007/10/02)

The O,S-dimethylphosphorochloridate 10 reacts with 5'-O-monomethoxytritylthymidine 11 in pyridine giving nucleoside-3'-thiolophosphodiester 13 in high yields ; in acetonitrile and in the presence of 1-methylimidazole, this reaction leads to the nucleoside-3'-phosphotriester 14 without formation of diester 13.From the latter, the Tp and TpT have been prepared.
