Benzyloxycarbonyl-L-glutaminyl-L-leucin-aethylester, also known as Z-Glu-Leu-OEt, is a tripeptide derivative that consists of three amino acids: glutamine, leucine, and a modified leucine with an ethyl ester group. The peptide is protected with a benzyloxycarbonyl (Z) group, which is commonly used in peptide synthesis to prevent unwanted side reactions and ensure the correct sequence of amino acids. Z-Glu-Leu-OEt is a valuable compound in the field of peptide chemistry, as it serves as a building block for the synthesis of larger peptides and proteins, and can be used in various biological and pharmaceutical applications, such as drug development and research on protein-protein interactions.
The CAS Registry Mumber 4124-68-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 4 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4124-68: (6*4)+(5*1)+(4*2)+(3*4)+(2*6)+(1*8)=69 69 % 10 = 9 So 4124-68-9 is a valid CAS Registry Number.
