The chemical sequence "Z-Cys(Bzl)-Tyr(Bzl)-Phe-Gln-Asn-Cys(Bzl)-Pro-D-Arg(TOS)-Gly-NH2" represents a peptide, which is a chain of amino acids. In this specific peptide, several amino acids are modified or protected with chemical groups to stabilize the structure or prevent unwanted reactions during synthesis. "Z" stands for a carbobenzoxy group, which is a protecting group for the N-terminus of the peptide. "Bzl" indicates a benzyl group, which is a protecting group for cysteine (Cys) and tyrosine (Tyr) residues, preventing them from forming unwanted disulfide bonds. "TOS" is a tosyl group, which is a protecting group for the arginine (Arg) side chain. "D-Arg(TOS)" signifies that the arginine is in its D-configuration, which is the mirror image of the naturally occurring L-arginine. The peptide ends with a glycine (Gly) residue and an amide group (NH2), which is characteristic of the C-terminus of many peptides. This particular sequence is likely designed for a specific biological function or as a component of a larger protein structure, with the protective groups ensuring that the peptide maintains its intended conformation during synthesis and subsequent use.

Check Digit Verification of cas no

The CAS Registry Mumber 58928-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,9,2 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58928-33:
(7*5)+(6*8)+(5*9)+(4*2)+(3*8)+(2*3)+(1*3)=169
169 % 10 = 9
So 58928-33-9 is a valid CAS Registry Number.
