Check Digit Verification of cas no

The CAS Registry Mumber 81793-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,9 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81793-93:
(7*8)+(6*1)+(5*7)+(4*9)+(3*3)+(2*9)+(1*3)=163
163 % 10 = 3
So 81793-93-3 is a valid CAS Registry Number.

THE PROTECTION OF URACIL AND GUANINE RESIDUES IN OLIGONUCLEOTIDE SYNTHESIS

Jones, Simon S.,Reese, Colin B.,Sibanda, Samson,Ubasawa, Aiko

, p. 4755 - 4758 (1981)

The protection of uracil and 2-N-acyl guanine residues with 4-O-phenyl and 6-O-(2-nitrophenyl) groups as in 7a (or 7b) and 9, respectively, is described.These O-aril protecting groups, which appear to withstand the usual conditions of oligonucleotide synthesis, may readily be removed by treatment with 2-nitrobenzaldoximate ions.
