Check Digit Verification of cas no

The CAS Registry Mumber 79827-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,2 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79827-19:
(7*7)+(6*9)+(5*8)+(4*2)+(3*7)+(2*1)+(1*9)=183
183 % 10 = 3
So 79827-19-3 is a valid CAS Registry Number.

Synthesis of 2',3'-Differentiated Ribonucleosides via Glycosylation. Reactions with 2-O-Me or 2-O-TBDMS Ribofuranose Derivatives. 1. Pyrimidine Series

Chavis, C.,Dumont, F.,Wightman, R. H.,Ziegler, J. C.,Imbach, J. L.

, p. 202 - 206 (1982)

The synthesis of 2',3' asymmetrically substituted pyrimidine ribonucleosides in 70-95percent yields by using modified Vorbruggen conditions with "nonparticipating" 2-O-CH3 and 2-O-TBDMS ribofuranoses is described.Such compounds are useful synthons for oligoribonucleotide synthesis, including incorporation of "rare" bases.New and practically useful conditions for placement (using 1,2,4-triazole) and removal (KF/crown ether) of the tert-butyldimethylsilyl (TBDMS) protecting group are also reported.
