The chemical sequence "Z(OMe)-Lys(Z)-Ala-Ile-Ala-Ala-Leu-Ala-Lys(Z)-Lys(Z)-Leu-Leu-NH2" represents a peptide, which is a chain of amino acids. In this specific peptide, several amino acids are linked together in a particular order. The sequence starts with Z(OMe)-Lys(Z), where "Z" is a protecting group used in peptide synthesis to prevent unwanted reactions, and "OMe" stands for methoxy group. The peptide then continues with the amino acids alanine (Ala), isoleucine (Ile), and three more alanines, followed by leucine (Leu), another alanine, and two lysines (Lys), each with a Z protecting group. The sequence ends with two leucines and a terminal amine group (NH2). This particular arrangement of amino acids may have specific biological activity or be part of a larger protein structure, but without additional context, it's challenging to provide a more detailed summary of its function or properties.
The CAS Registry Mumber 79396-72-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,3,9 and 6 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 79396-72: (7*7)+(6*9)+(5*3)+(4*9)+(3*6)+(2*7)+(1*2)=188 188 % 10 = 8 So 79396-72-8 is a valid CAS Registry Number.
