The chemical "Z-Arg(NO2)-5-Ava-Gly-Phe-Ser-Pro-Phe-Arg(NO2)-OBzl" is a complex peptide sequence with a molecular structure that includes several amino acids and functional groups. It is characterized by the presence of two arginine (Arg) residues, each with a nitro group (NO2), which is a common modification used to study the effects of electron-withdrawing groups on peptide reactivity and stability. The sequence also includes 5-aminovaleric acid (5-Ava), a non-natural amino acid that can be incorporated into peptides to alter their properties. The other amino acids in the sequence are glycine (Gly), phenylalanine (Phe), serine (Ser), proline (Pro), and another phenylalanine (Phe). The peptide is capped with a benzyl (OBzl) group, which is often used to protect the peptide's terminal amino group during synthesis. This specific sequence and its modifications are likely designed for a particular biological or chemical application, such as studying peptide-protein interactions, drug development, or understanding the effects of specific amino acid substitutions on peptide conformation and function.
The CAS Registry Mumber 76546-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,4 and 6 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 76546-53: (7*7)+(6*6)+(5*5)+(4*4)+(3*6)+(2*5)+(1*3)=157 157 % 10 = 7 So 76546-53-7 is a valid CAS Registry Number.
