Check Digit Verification of cas no

The CAS Registry Mumber 144744-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144744-45:
(8*1)+(7*4)+(6*4)+(5*7)+(4*4)+(3*4)+(2*4)+(1*5)=136
136 % 10 = 6
So 144744-45-6 is a valid CAS Registry Number.

Synthesis of Optically Active Arylglycines by Photolysis of Optically Active (β-Hydroxyamino) Carbene-Chromium(0) Complexes

Vernier, Jean-Michel,Hegedus, Louis S.,Miller, David B.

, p. 6914 - 6920 (2007/10/02)

Photolysis of chromium complexes having the optically active amino alcohol (1R,2S)-(-)- or (1S,2R)-(+)-2-amino-1,2-diphenylethanol as the amino group produced aryl-substituted oxazinones in good yield with reasonable diastereoselectivity.Facile separation of diastereoisomers followed by mild reductive cleavage produced several arylglycines, having either electron-donating or withdrawing groups on the aromatic ring, in good overall yield and with excellent enantiomeric excess.
