"Z(OMe)-Arg(Mts)-Ile-NHNH2" is a peptide compound consisting of four amino acid residues: Z(OMe), Arg(Mts), Ile, and NHNH2. Z(OMe) represents a protected form of the amino acid methionine, where the sulfur atom is blocked by a methyl group (OMe). Arg(Mts) is a modified form of the amino acid arginine, with a methanethiosulfonate (Mts) group attached to the guanidinium group. Ile stands for isoleucine, a hydrophobic amino acid. The NHNH2 at the end indicates a terminal amine group, which is characteristic of peptides. This specific sequence and modification pattern suggest that the compound may have unique properties or be designed for a specific biological interaction or study, potentially in the context of drug design or protein chemistry.
The CAS Registry Mumber 99236-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,3 and 6 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 99236-64: (7*9)+(6*9)+(5*2)+(4*3)+(3*6)+(2*6)+(1*4)=173 173 % 10 = 3 So 99236-64-3 is a valid CAS Registry Number.
