82009-52-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82009-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82009-52:
(7*8)+(6*2)+(5*0)+(4*0)+(3*9)+(2*5)+(1*2)=107
107 % 10 = 7
So 82009-52-7 is a valid CAS Registry Number.

Chiral Lactols, II. Racemate Separation and Enantioselective Acetalisation with the 2,3,3a,4,5,6,7,7a-Octahydro-7,8,8-trimethyl-4,7-methanobenzofuran-2-yl Protective Group

Noe, Christian R.

, p. 1591 - 1606 (2007/10/02)

A simple method for the resolution of the chiral alcohols, cyanohydrins, thiols and amines rac-2a - f by the reaction with the chiral protective group 1a ( or 1b, respectively) is described.The diastereomeric derivatives 3a - f and 4a - f are separated by column chromatography or crystallisation.Subsequent methanolysis or hydrolysis, respectively, yields the enantiomers and the recovered protective group.With rac-2a - c preferential acetalisation of the (R)-enantiomers was observed.This phenomenon was investigated by modification of the protective group.Considerations on conformations of 3a point to an important role of the anomeric and exo-anomeric effect in this enantioselective reaction.
