The chemical sequence "Z-Cys(Bzl)-Tyr(Bzl)-Phe-Gln-Asn-Cys(Bzl)-Pro-Leu-β-Ala-NH2" represents a peptide, which is a short chain of amino acids. In this specific peptide, several amino acids are present, each with unique side chains that contribute to the overall properties of the molecule. Cysteine (Cys) residues are modified with benzyl (Bzl) groups, which protect the thiol groups and prevent disulfide bond formation until the protecting groups are removed. Tyrosine (Tyr) is also benzylated, which similarly protects its hydroxyl group. Phenylalanine (Phe), glutamine (Gln), asparagine (Asn), proline (Pro), and leucine (Leu) are included in their unmodified forms, contributing to the peptide's structure and function. β-Alanine is a non-proteinogenic amino acid, which means it is not commonly found in proteins but can be incorporated into peptides for specific purposes. The peptide is capped with a carboxy-terminal amide group (NH2), which can affect its solubility and reactivity. This sequence is likely designed for a specific biological function or as a component of a larger peptide or protein structure, with the protecting groups allowing for controlled synthesis and modification.

78398-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78398-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,9 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.Calculate Digit Verification of CAS Registry Number 78398-15:
(7*7)+(6*8)+(5*3)+(4*9)+(3*8)+(2*1)+(1*5)=179
179 % 10 = 9
So 78398-15-9 is a valid CAS Registry Number.
