Check Digit Verification of cas no

The CAS Registry Mumber 197719-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,1 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 197719-54:
(8*1)+(7*9)+(6*7)+(5*7)+(4*1)+(3*9)+(2*5)+(1*4)=193
193 % 10 = 3
So 197719-54-3 is a valid CAS Registry Number.

Facile preparation of protected furanoid glycals from thymidine

Cameron, Melissa A.,Cush, Sarah B.,Hammer, Robert P.

, p. 9065 - 9069 (1997)

The synthesis of O-silyl- and O-acyl-protected furanose glycals from free thymidine was investigated. The method of glycal formation reported by Pedersen et al. was successfully expanded to include 5-ester (toluoyl) protected glycals as well as various combinations of 5'-ester and 3- and 5- tert-butyldimethylsilyl and tert-butyldiphenylsilyl protection. Gram quantities of furanoid glycals can be prepared in a few days in two-four steps in overall yields ranging from 17 to 80%.
