The chemical sequence "Z(OMe)-Asp(OBzl)-Val-His-Asn-Phe-Val-Ala-Leu-Gly-OBzl" represents a peptide, which is a chain of amino acids. In this specific peptide, the amino acids are linked together in the following order: Valine (Val), Aspartic acid (Asp), Histidine (His), Asparagine (Asn), Phenylalanine (Phe), Valine (Val), Alanine (Ala), Leucine (Leu), and Glycine (Gly). The "Z(OMe)" and "OBzl" groups are protecting groups used in peptide synthesis. "Z(OMe)" is a benzyloxycarbonyl group with a methoxy substituent, which protects the N-terminus of the peptide, while "OBzl" is a benzyl group that protects the side chain of aspartic acid. These protecting groups are crucial for preventing unwanted side reactions during the synthesis process and are later removed to yield the final peptide product. This particular peptide sequence, with its specific arrangement of amino acids and protective groups, is likely designed for a specific biological function or as a component of a larger protein structure.
The CAS Registry Mumber 82882-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,8 and 2 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 82882-86: (7*8)+(6*2)+(5*8)+(4*8)+(3*2)+(2*8)+(1*6)=168 168 % 10 = 8 So 82882-86-8 is a valid CAS Registry Number.
