Check Digit Verification of cas no

The CAS Registry Mumber 215436-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,4,3 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 215436-53:
(8*2)+(7*1)+(6*5)+(5*4)+(4*3)+(3*6)+(2*5)+(1*3)=116
116 % 10 = 6
So 215436-53-6 is a valid CAS Registry Number.

A new strategy for the asymmetric synthesis of 1,3-oxathiolane-based nucleoside analogues

Caputo, Romualdo,Guaragna, Annalisa,Palumbo, Giovanni,Pedatella, Silvana

, p. 1455 - 1458 (2007/10/03)

A ready asymmetric synthesis of 3'-oxathionucleosides has been accomplished in three main steps from benzoyloxyethanal. The synthesis is characterized by high overall yield and considerable enantiomeric excesses. It represents a general synthetic path to prepare a wide range of heterosubstituted sulfur-containing nucleoside analogues.
