Z-Gly-Lys(Ac) is a synthetic peptide consisting of three amino acids: glycine (Gly), lysine (Lys), and acetylated lysine (Lys(Ac)). The "Z" group is a protecting group, which is a chemical moiety used to temporarily block certain functional groups during peptide synthesis. In this case, it is attached to the N-terminus of the peptide, protecting the amino group of glycine. The acetyl group (Ac) is attached to the epsilon amino group of lysine, which is the second amino acid in the sequence. This specific arrangement of amino acids and protective groups is crucial for the peptide's stability and reactivity during synthesis, and it can be used in various applications, such as studying protein-protein interactions or as a building block in the synthesis of larger peptides and proteins.
The CAS Registry Mumber 95364-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,3,6 and 4 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 95364-66: (7*9)+(6*5)+(5*3)+(4*6)+(3*4)+(2*6)+(1*6)=162 162 % 10 = 2 So 95364-66-2 is a valid CAS Registry Number.
