The chemical "Z(OMe)-Lys(Z)-Pro-Asp(OBzl)-Gln-Phe-Val-Gly-Leu-Met-NH2" is a peptide sequence consisting of eleven amino acids. It is a synthetic compound that incorporates various protecting groups to facilitate its synthesis and stability. The "Z" group is a benzyloxycarbonyl (Cbz) protecting group, which is commonly used to protect the amino group of lysine and aspartic acid. The "OMe" indicates that the protecting group is attached to the oxygen atom of the side chain. The "Pro" stands for proline, "Asp(OBzl)" signifies aspartic acid with a benzyl (OBzl) protecting group on its carboxylic acid, and "Gln" is glutamine. "Phe" is phenylalanine, "Val" is valine, "Gly" is glycine, "Leu" is leucine, and "Met" is methionine. The "NH2" at the end indicates that the peptide has a free amino group, suggesting it is a C-terminal amino acid. This peptide sequence is likely used in research or pharmaceutical development, possibly as a precursor to a larger protein or for studying peptide-protein interactions.
The CAS Registry Mumber 89671-26-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,7 and 1 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 89671-26: (7*8)+(6*9)+(5*6)+(4*7)+(3*1)+(2*2)+(1*6)=181 181 % 10 = 1 So 89671-26-1 is a valid CAS Registry Number.
