"Z(OMe)-Ile-Ala-Ala-NH-NH2" is a peptide compound consisting of four amino acids: Isoleucine (Ile), Alanine (Ala), Alanine (Ala), and a terminal amino group (NH2). The "Z(OMe)" prefix indicates that the N-terminal amino group is protected by a carbobenzoxy (Cbz) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. This specific peptide is a linear sequence of amino acids, which are the building blocks of proteins. The sequence is characterized by the presence of two alanine residues, which are nonpolar amino acids, and one isoleucine, a hydrophobic amino acid. The terminal amino group suggests that this peptide could be a precursor to a larger peptide or protein, or it could be used in chemical reactions where the free amino group is required. The structure and properties of this peptide would be influenced by the specific arrangement of these amino acids and the protective group at the N-terminus.
The CAS Registry Mumber 74105-00-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,0 and 5 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 74105-00: (7*7)+(6*4)+(5*1)+(4*0)+(3*5)+(2*0)+(1*0)=93 93 % 10 = 3 So 74105-00-3 is a valid CAS Registry Number.
