Check Digit Verification of cas no

The CAS Registry Mumber 190506-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,5,0 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 190506-34:
(8*1)+(7*9)+(6*0)+(5*5)+(4*0)+(3*6)+(2*3)+(1*4)=124
124 % 10 = 4
So 190506-34-4 is a valid CAS Registry Number.

A high-yield synthesis of deoxy-2-fluoroinosine and its incorporation into oligonucleotides

Adib, Abdennaji,Potier, Pierre F.,Doronina, Svetlana,Huc, Ivan,Behr, Jean-Paul

, p. 2989 - 2992 (1997)

An improved synthesis of the deoxy-2-fluoroinosine nucleoside is described, that makes use of mild fluorination (polyvinylpyridinium polyhydrogenfluoride) and O-silyl deprotection (triethylamine trihydrofluoride) reactions. The derived 5'-dimethoxytrityl-
