Check Digit Verification of cas no

The CAS Registry Mumber 199528-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,5,2 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199528-65:
(8*1)+(7*9)+(6*9)+(5*5)+(4*2)+(3*8)+(2*6)+(1*5)=199
199 % 10 = 9
So 199528-65-9 is a valid CAS Registry Number.

Synthesis of 3′-thioribouridine, 3′-thioribocytidine, and their phosphoramidites

Sun, Sengen,Piccirilli, Joseph A.

, p. 1543 - 1545 (1997)

3′-Thio-3′-deoxyribonucleosides (U and C) have been synthesized via Vorbruggen-type glycosylation with 3-S-benzoyl-5-O-toluoyl-1,2-O-diacetylfuranose, which was obtained from 1,2-O-isopropylidene-5-O-toluoyl-3-O-trifluoromethanesulfonyl-α-D- xylofuranose. 3′-Thio-3′-deoxyuridine has been converted to its phosphoramidite.
