"Z(OMe)-Ser(Bzl)-Phe-His-NHNH2" is a peptide compound consisting of five amino acid residues: Z(OMe)-Ser, Bzl-Phe, His, and NHNH2. Z(OMe)-Ser refers to O-Methyl-L-Tyrosine, a derivative of the amino acid serine with a methyl group attached to the hydroxyl group. Bzl-Phe represents phenylalanine with a benzyl group attached to its side chain, which can influence the peptide's properties. His stands for histidine, an amino acid with an imidazole side chain that can participate in hydrogen bonding and metal ion coordination. The NHNH2 group at the end of the peptide is a terminal amine group, which can be involved in various chemical reactions and interactions. This specific sequence and modification of amino acids may confer unique biological activities or stability to the peptide, depending on its intended application in research or therapeutics.
The CAS Registry Mumber 98477-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 7 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 98477-89: (7*9)+(6*8)+(5*4)+(4*7)+(3*7)+(2*8)+(1*9)=205 205 % 10 = 5 So 98477-89-5 is a valid CAS Registry Number.
