The chemical "(Boc)2Lys-Asp(OCMe3)-Ala-Phe-Ile-Gly-Leu-Met-NH2" is a peptide compound consisting of a sequence of nine amino acids. It is a derivative of a naturally occurring peptide, with modifications to enhance stability or functionality. The "(Boc)2Lys" indicates that the lysine amino acid has two tert-butyloxycarbonyl (Boc) protecting groups, which are commonly used in peptide synthesis to protect the amino group. "Asp(OCMe3)" signifies that the aspartic acid has a trimethyl ester group, which can protect the carboxylic acid group and may influence the peptide's reactivity or solubility. The sequence of amino acids that follows—Ala, Phe, Ile, Gly, Leu, and Met—contributes to the peptide's overall structure and potential biological activity. The "NH2" at the end indicates that the peptide has a free amine group, which is typical for the C-terminus of a peptide. This specific sequence and modification may be designed for a particular application in biochemistry, pharmacology, or materials science, such as a drug candidate, a molecular probe, or a component in a biomaterials application.
The CAS Registry Mumber 2642-34-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2642-34: (6*2)+(5*6)+(4*4)+(3*2)+(2*3)+(1*4)=74 74 % 10 = 4 So 2642-34-4 is a valid CAS Registry Number.
