"Z-Ile-Arg(Mds)-Pro-OBut" is a peptide compound consisting of four amino acids: Isoleucine (Ile), Arginine with a 4-methylcoumaryl-7-amide (Mds) modification, Proline (Pro), and a butyl ester (OBut) group. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence and modification are designed for research purposes, potentially for studying protein-protein interactions, enzyme substrate specificity, or as a component in drug development. The Mds group, in particular, may be used for fluorescence-based assays or as a reporter group to track the peptide's behavior in biological systems.
The CAS Registry Mumber 80220-14-0 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 4 respectively. Calculate Digit Verification of CAS Registry Number 80220-14: (7*8)+(6*0)+(5*2)+(4*2)+(3*0)+(2*1)+(1*4)=80 80 % 10 = 0 So 80220-14-0 is a valid CAS Registry Number.
