"Z-Pro-Phe-MeArg(Tos)-OBzl" is a peptide compound consisting of four amino acid residues: N-benzyloxycarbonyl (Z) protected proline (Pro), phenylalanine (Phe), N-methylated arginine (MeArg) with a tosyl group (Tos), and benzyl (OBzl) protected at the C-terminus. This specific sequence and protection pattern are often used in peptide synthesis to facilitate the stepwise assembly of larger peptide chains. The benzyl group (OBzl) at the C-terminus serves as a temporary protecting group that can be removed under specific conditions to allow further elongation of the peptide chain. The tosyl group on the arginine side chain is a protecting group that can be selectively removed to reveal a free amine group, which is crucial for peptide bond formation. Z-Pro-Phe-MeArg(Tos)-OBzl is a building block in the synthesis of more complex peptides and proteins, and its protected nature allows for controlled and efficient synthesis processes.

Check Digit Verification of cas no

The CAS Registry Mumber 74071-93-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,7 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74071-93:
(7*7)+(6*4)+(5*0)+(4*7)+(3*1)+(2*9)+(1*3)=125
125 % 10 = 5
So 74071-93-5 is a valid CAS Registry Number.
