The chemical sequence "Z(OMe)-Ala-Ile-Asp(OChp)-Asn-His-Arg(Mts)-NHNH₂" represents a peptide with a specific structure. It is composed of several amino acids, each denoted by its three-letter code, and includes modifications to some of these amino acids. "Z(OMe)" indicates that the N-terminal amino acid, alanine (Ala), is protected with a carbobenzoxy (Cbz) group, which is a common protecting group in peptide synthesis, and "OMe" suggests the presence of a methoxy group. Isoleucine (Ile) follows alanine, and aspartic acid (Asp) is modified with a chlorophenylalanine (OChp) group. Asparagine (Asn) and histidine (His) are present next, with arginine (Arg) being modified with a methanethiosulfonate (Mts) group, which is a thiol-reactive group used for cysteine modification. The peptide ends with a hydrazide group (NHNH₂), which can be used for further conjugation or stabilization. This sequence is likely part of a larger bioactive molecule or a component in a drug design, with the modifications serving specific purposes such as protecting reactive groups during synthesis, enhancing stability, or improving pharmacokinetic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 98477-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,7 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98477-88:
(7*9)+(6*8)+(5*4)+(4*7)+(3*7)+(2*8)+(1*8)=204
204 % 10 = 4
So 98477-88-4 is a valid CAS Registry Number.
