α-Benzyloxycarbonyl-amino-isobutyryl-DL-phenylalanin-methylester, also known as Z-Aib-Phe-OMe, is a synthetic peptide derivative that consists of three amino acid residues: phenylalanine, isobutyryl, and α-aminoisobutyryl. The molecule is characterized by the presence of a benzyloxycarbonyl (Z) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. The isobutyryl group is a non-standard amino acid residue, providing unique properties to the peptide. The phenylalanine residue is a natural amino acid, while the α-aminoisobutyryl group is a modified version of isobutyric acid. The methylester group at the end of the peptide chain indicates that the carboxyl group has been esterified with methanol. α-Benzyloxycarbonyl-amino-isobutyryl-DL-phenylalanin-methylester is often used in peptide synthesis and research, particularly in the study of peptide conformation and folding, as well as in the development of new drugs and bioactive molecules.
The CAS Registry Mumber 15030-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,3 and 0 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 15030-78: (7*1)+(6*5)+(5*0)+(4*3)+(3*0)+(2*7)+(1*8)=71 71 % 10 = 1 So 15030-78-1 is a valid CAS Registry Number.
