Z-Pro-Leu-Leu-OEt is a synthetic tetrapeptide, consisting of four amino acid residues: pyrrolidone carboxylic acid (Z), proline (Pro), leucine (Leu), and leucine (Leu), with an ethyl ester (OEt) group at the C-terminus. This peptide is known for its potential applications in various fields, such as pharmaceuticals, agrochemicals, and materials science. It is often used as a building block for the synthesis of larger peptides or as a precursor in the development of peptide-based drugs. The presence of the ethyl ester group allows for controlled release and improved bioavailability of the peptide in biological systems. Z-Pro-Leu-Leu-OEt is also of interest in research due to its potential role in modulating biological processes and its ability to interact with specific receptors or enzymes.

Check Digit Verification of cas no

The CAS Registry Mumber 21687-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,8 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21687-98:
(7*2)+(6*1)+(5*6)+(4*8)+(3*7)+(2*9)+(1*8)=129
129 % 10 = 9
So 21687-98-9 is a valid CAS Registry Number.
