208458-85-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 208458-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,4,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 208458-85:
(8*2)+(7*0)+(6*8)+(5*4)+(4*5)+(3*8)+(2*8)+(1*5)=149
149 % 10 = 9
So 208458-85-9 is a valid CAS Registry Number.

Imidazo-oxazaphosphorines as precursors to chiral phosphite triesters
Marsault, Eric,Just, George
, p. 939 - 955 (2007/10/03)
New bicyclic imidazo-oxazaphosphorines underwent a highly diastereoselective displacement of the imidazole moiety upon reaction with various alcohols, leading to chiral phosphite triesters as single diastereomers. The introduction of a nucleoside on this
