"Z(OMe)-Arg(Mts)-Leu-NH2" is a peptide compound consisting of four amino acid residues: Z(OMe), Arg(Mts), Leu, and NH2. 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. Leu stands for leucine, an amino acid with a hydrophobic side chain. The NH2 at the end indicates that the peptide has a free amino group, making it an amide. This specific sequence and modification of amino acids may have unique properties and applications in fields such as drug development, chemical biology, or as a research tool in peptide chemistry.
The CAS Registry Mumber 90984-08-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,8 and 4 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 90984-08: (7*9)+(6*0)+(5*9)+(4*8)+(3*4)+(2*0)+(1*8)=160 160 % 10 = 0 So 90984-08-0 is a valid CAS Registry Number.
