"Z-Arg(Mds)-Ile-Arg(Mds)-Pro-OBut" is a synthetic peptide consisting of five amino acid residues: Z-protected arginine (Arg), isoleucine (Ile), and arginine with a 4-methylbenzenesulfonyl (Mds) group, proline (Pro), and a butyl ester (OBut) at the C-terminus. This specific sequence and modification are designed to study protein-protein interactions, enzymatic activity, or as a potential therapeutic agent. The Mds group is a bulky protecting group that can influence the peptide's conformation and reactivity, while the butyl ester group may aid in solubility or stability. The peptide's properties and applications can vary widely depending on the context in which it is used, such as in drug development, biochemical research, or as a tool in understanding protein structure and function.
The CAS Registry Mumber 80220-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,2 and 0 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 80220-16: (7*8)+(6*0)+(5*2)+(4*2)+(3*0)+(2*1)+(1*6)=82 82 % 10 = 2 So 80220-16-2 is a valid CAS Registry Number.
