Check Digit Verification of cas no

The CAS Registry Mumber 1013088-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,3,0,8 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1013088-41:
(9*1)+(8*0)+(7*1)+(6*3)+(5*0)+(4*8)+(3*8)+(2*4)+(1*1)=99
99 % 10 = 9
So 1013088-41-9 is a valid CAS Registry Number.

Enantioselective synthesis of α-fluorinated β2-amino acids

Edmonds, Michael K.,Graichen, Florian H.M.,Gardiner, James,Abell, Andrew D.

, p. 885 - 887 (2008)

A methodology for the enantioselective synthesis of α-fluorinated β2-amino acids has been developed from readily available carboxylic acids 3. Conversion to the Evan's oxazolidinone followed by enantioselective fluorination and alkylation gave 7 in high diastereomeric excess (>95%). Subsequent removal of the oxazolidinone and amination at the Bn-protected hydroxyl center gave optically active α-fluorinated β2-amino acids.
