Z-Orn(-Phth)-Gly-NH2 is a synthetic peptide compound consisting of four amino acid residues: Z (benzyloxycarbonyl), Orn (ornithine), Phth (phenylthiocarbamoyl), Gly (glycine), and NH2 (amide group). The Z group is a protecting group used in peptide synthesis to prevent unwanted side reactions, while Orn is a non-proteinogenic amino acid. The Phth group is a phenylthiocarbamoyl protecting group for the ornithine side chain, and Gly is a simple amino acid. The NH2 group indicates the presence of a free amine group at the C-terminus of the peptide. Z-Orn(-Phth)-Gly-NH2 is often used in peptide synthesis and research, particularly in the study of protein-protein interactions and the development of novel therapeutic agents.
The CAS Registry Mumber 7767-02-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 7 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7767-02: (6*7)+(5*7)+(4*6)+(3*7)+(2*0)+(1*2)=124 124 % 10 = 4 So 7767-02-4 is a valid CAS Registry Number.
