Check Digit Verification of cas no
The CAS Registry Mumber 138775-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,7 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138775-54:
(8*1)+(7*3)+(6*8)+(5*7)+(4*7)+(3*5)+(2*5)+(1*4)=169
169 % 10 = 9
So 138775-54-9 is a valid CAS Registry Number.

The facile synthesis of a series of tryptophan derivatives
Blaser, Georg,Sanderson, John M.,Batsanov, Andrei S.,Howard, Judith A.K.
, p. 2795 - 2798 (2008/09/19)
This study reports a facile method for the synthesis of a variety of 5- and 6-substituted tryptophan derivatives that are difficult to prepare using alternative enzymatic approaches. Acylation of an activated amino acid, derived from serine in situ, is coupled with an enzymatic resolution step to furnish enantiopure analogues bearing a range of electron withdrawing and releasing substituents. Isolation of a dehydroalanine derivative as a by-product from some reactions provides some insights into the likely mechanism of the reaction.
