Check Digit Verification of cas no

The CAS Registry Mumber 1200119-13-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,0,1,1 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1200119-13:
(9*1)+(8*2)+(7*0)+(6*0)+(5*1)+(4*1)+(3*9)+(2*1)+(1*3)=66
66 % 10 = 6
So 1200119-13-6 is a valid CAS Registry Number.

Stereoselective construction of 1β-azido- And 1β-cyano-2-deoxyribose derivatives

A new method has been developed for the β-selective introduction of azido and cyano groups at the anomeric position of 2-deoxyribose derivatives. This method proceeds via the formation of a collidinium salt intermediate and allows for the stereoselective construction of 1β-azido- and 1β-cyano-2-deoxy-D-ribose derivatives. 2-Deoxy-D-ribose compounds bearing an acetoxy or tert-butoxycarbonyloxy group at their anomeric position performed well as starting materials for the formation of the corresponding 1β-azide and 1β-cyanide derivatives, respectively. 1H NMR studies of the salt intermediates revealed that the nucleophilic substitution reaction of the salt intermediates proceeded in a SN2-fashion.
