Z-Gln-Arg(Tos)-Leu-OH is a synthetic peptide consisting of four amino acids: glutamine (Gln), arginine with a tosyl group (Arg(Tos)), and leucine (Leu), with a hydroxyl group (OH) at the end. The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids is known for its potential biological activities, such as acting as a substrate for certain enzymes or receptors, and it is often used in research to study peptide-protein interactions, drug design, and other biochemical processes. The tosyl group on the arginine residue can be used as a handle for further modifications or as a protecting group that can be removed under specific conditions to reveal a free amine group.

Check Digit Verification of cas no

The CAS Registry Mumber 83077-76-3 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, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83077-76:
(7*8)+(6*3)+(5*0)+(4*7)+(3*7)+(2*7)+(1*6)=143
143 % 10 = 3
So 83077-76-3 is a valid CAS Registry Number.
