Check Digit Verification of cas no

The CAS Registry Mumber 76887-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,8 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76887-35:
(7*7)+(6*6)+(5*8)+(4*8)+(3*7)+(2*3)+(1*5)=189
189 % 10 = 9
So 76887-35-9 is a valid CAS Registry Number.

REACTION BETWEEN 1-ARENESULPHONYL-3-NITRO-1,2,4-TRIAZOLES AND NUCLEOSIDE BASE RESIDUES. ELUCIDATION OF THE NATURE OF SIDE-REACTIONS DURING OLIGONUCLEOTIDE SYNTHESIS.

Reese, Colin B.,Ubasawa, Aiko

, p. 2265 - 2268 (1980)

The protected guanosine and uridine derivatives (3a, 3b, and 4) react with 1-(mesitylene-2-sulphonyl)-3-nitro-1,2,4-triazole (MSNT, 2a) to give 5a, 5b and 7, respectively; 9 is converted into 10 in the same way.The reactions proceed more rapidly in the presence of diphenyl phosphate.
