Z-Arg(Tos)-Leu-OBzl is a peptide compound consisting of three amino acids: Z-protected arginine (Arg), tosyl group (Tos), leucine (Leu), and benzyl-protected (OBzl). This specific sequence is often used in peptide synthesis, where the Z group is a protecting group that shields the amino group of the arginine from unwanted reactions until the desired peptide bond formation occurs. The tosyl group is another protecting group, in this case, for the side chain of the arginine. The benzyl group (OBzl) protects the carboxylic acid group of the leucine, preventing it from reacting until the peptide chain is fully assembled. Z-Arg(Tos)-Leu-OBzl is a building block in the synthesis of larger peptides and proteins, and the protecting groups are crucial for controlling the reaction conditions and ensuring the correct sequence of amino acids is formed.

Check Digit Verification of cas no

The CAS Registry Mumber 83077-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,7 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83077-89:
(7*8)+(6*3)+(5*0)+(4*7)+(3*7)+(2*8)+(1*9)=148
148 % 10 = 8
So 83077-89-8 is a valid CAS Registry Number.
