Check Digit Verification of cas no
The CAS Registry Mumber 57213-14-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,1 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57213-14:
(7*5)+(6*7)+(5*2)+(4*1)+(3*3)+(2*1)+(1*4)=106
106 % 10 = 6
So 57213-14-6 is a valid CAS Registry Number.

Preparation of L (4 azido 2 nitrophenyl)alanine as label for amino acid transport systems in biological membranes
Fahrenholz,Schimmack
, p. 469 - 471 (1975)
The synthesis of 4' azido 2' nitro L phenyl alanine is described. It could be activated by irradiation (λ > 345 nm) within a few minutes and can thus possibly be used for labeling amino acid transport systems in biological membranes.
