"Z-Arg(Mts)-Arg(Mts)-Pro-OBzl" is a peptide compound consisting of four amino acids: two Arginine (Arg) residues with a 4-methyltrityl (Mts) protecting group, one Proline (Pro) residue, and a benzyl ester (OBzl) protecting group at the C-terminus. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Cbz) protecting group on the N-terminus. This specific sequence and the presence of protecting groups make it a valuable compound in peptide synthesis, particularly for the study of protein structure and function, as well as for the development of pharmaceuticals. The Mts group is used to protect the guanidinium group of the arginine residues, which is crucial for preventing unwanted side reactions during peptide synthesis. The OBzl group, on the other hand, serves to protect the carboxyl group of the peptide, ensuring that it remains stable until the desired point in the synthesis process.
The CAS Registry Mumber 82101-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,0 and 1 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 82101-64: (7*8)+(6*2)+(5*1)+(4*0)+(3*1)+(2*6)+(1*4)=92 92 % 10 = 2 So 82101-64-2 is a valid CAS Registry Number.
