The chemical "Z(OMe)-Lys(Z)-Ala-Leu-Ala-Ala-Leu-Ala-Lys(Z)-Lys(Z)-Ile-Leu-NH2" is a peptide compound consisting of a sequence of amino acids. It features a protected lysine residue at the N-terminus with a Z(OMe) group, which is a benzyl-based protecting group commonly used in peptide synthesis to prevent unwanted side reactions. The sequence includes alanine (Ala), leucine (Leu), and isoleucine (Ile), which are nonpolar amino acids, contributing to the hydrophobic nature of the peptide. The presence of two lysine residues, each with a Z group, suggests that this peptide may be designed for specific interactions or modifications, such as crosslinking or conjugation. The Z group on lysine is a temporary protecting group that can be removed under mild acidic conditions to reveal the free amino group, allowing for further chemical reactions. The peptide ends with a leucine residue and an amide group (NH2), indicating a C-terminal amide. This specific sequence and the presence of protecting groups suggest that the peptide is intended for use in advanced chemical synthesis, potentially for pharmaceutical or biotechnological applications.
The CAS Registry Mumber 74496-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,9 and 6 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 74496-45: (7*7)+(6*4)+(5*4)+(4*9)+(3*6)+(2*4)+(1*5)=160 160 % 10 = 0 So 74496-45-0 is a valid CAS Registry Number.
