"Z(OMe)-(Gly-Lys(Z)-Gly)2-OBzl" is a complex peptide compound consisting of a central Z(OMe) group, which is a protecting group used in peptide synthesis, and two identical peptide sequences, (Gly-Lys(Z)-Gly), attached to it. The Gly represents glycine, an amino acid, while Lys(Z) denotes a lysine residue with a Z group, another protecting group, attached to its side chain. The OBzl at the end signifies a benzyl ester group, which is often used to protect the carboxylic acid group in peptide synthesis. Z(OMe)-(Gly-Lys(Z)-Gly)2-OBzl is significant in the field of organic chemistry and biochemistry, particularly in the synthesis of peptides and proteins, as it allows for the controlled assembly of amino acids into specific sequences while protecting reactive groups from unwanted side reactions.
The CAS Registry Mumber 16964-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,6 and 4 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 16964-77: (7*1)+(6*6)+(5*9)+(4*6)+(3*4)+(2*7)+(1*7)=145 145 % 10 = 5 So 16964-77-5 is a valid CAS Registry Number.
