The given sequence "Z(OMe)-Asn-Asn-Phe-Val-Pro-Thr-Asn-Val-Gly-Ser(Bzl)-Lyz(Z)-Ala-Phe-NH2" represents a peptide, which is a chain of amino acids. This particular peptide is composed of the following amino acids in order: N-benzyloxycarbonyl-protected serine (Ser(Bzl)), N-benzyloxycarbonyl-protected lysine (Lyz(Z)), and the other unmodified amino acids: asparagine (Asn), phenylalanine (Phe), valine (Val), proline (Pro), threonine (Thr), glycine (Gly), alanine (Ala), and a terminal amide group (NH2). The "Z(OMe)" at the beginning indicates that the peptide is protected at the N-terminus with a carbobenzoxy group (Cbz) and a methoxy group (OMe). This protection is often used in peptide synthesis to prevent unwanted side reactions. The peptide is a linear sequence of 15 amino acids, which could be part of a larger protein or a bioactive peptide with specific functions.
The CAS Registry Mumber 98748-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,4 and 8 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 98748-37: (7*9)+(6*8)+(5*7)+(4*4)+(3*8)+(2*3)+(1*7)=199 199 % 10 = 9 So 98748-37-9 is a valid CAS Registry Number.
