Z-L-MeAla-L-AlaOMe is a synthetic peptide compound consisting of three amino acid residues: Z-L-MeAla (N-benzyloxycarbonyl-L-methionine), L-Ala (L-alanine), and OMe (methoxy group). Z-L-MeAla-L-AlaOMe is characterized by its unique structure, where the N-terminal methionine is protected by a benzyloxycarbonyl (Z) group, and the side chain of the methionine is methylated (Me). The presence of L-alanine and a methoxy group at the C-terminus further contributes to its distinct properties. Z-L-MeAla-L-AlaOMe is often used in peptide synthesis and as a building block for the development of novel bioactive molecules, owing to its stability and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 81156-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,5 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81156-12:
(7*8)+(6*1)+(5*1)+(4*5)+(3*6)+(2*1)+(1*2)=109
109 % 10 = 9
So 81156-12-9 is a valid CAS Registry Number.

Assessment of Racemisation in N-Alkylated Amino-acid Derivatives during Peptide Coupling in a Model Dipeptide System

Davies, John S.,Mohammed, A. Karim

, p. 2982 - 2990 (2007/10/02)

N.m.r. analysis of diastereoisomeric benzoyl dipeptide esters has been used to monitor racemisation during the coupling of benzoyl-N-alkylated amino-acids to alanine and valine methyl esters.Results confirm the greater susceptibility of these amino-acids
