127358-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127358-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,3,5 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127358-18:
(8*1)+(7*2)+(6*7)+(5*3)+(4*5)+(3*8)+(2*1)+(1*8)=133
133 % 10 = 3
So 127358-18-3 is a valid CAS Registry Number.

Asymmetric synthesis of arylglycines
Williams,Hendrix
, p. 3723 - 3727 (2007/10/02)
The asymmetric synthesis of several arylglycines are reported. The methodology deployed involves either cuprate or Friedel - Crafts couplings to chiral bromoglycinates. The % ee's range from 82 to 94%. Both an oxidative and reductive protocol are employed to unmask the oxazinone chiral auxilliary providing the free α-amino acids.
