"Z-Lys(Z)-Cys(Bzl)-NH-NH2" is a peptide compound consisting of three amino acids: lysine (Lys), cysteine (Cys), and a terminal amine group (NH2). The lysine is modified with a benzyloxycarbonyl (Z) group, and the cysteine is protected with a benzyl (Bzl) group. These modifications are commonly used in peptide synthesis to protect reactive side chains and facilitate controlled coupling reactions. The compound is a linear peptide with a free amine group at the C-terminus, indicating that it could be a precursor in the synthesis of larger peptides or proteins. The presence of a cysteine residue suggests that this peptide may be involved in disulfide bond formation, which is crucial for the stability and function of many proteins. The Z and Bzl protecting groups are temporary and are removed during the final stages of peptide synthesis to yield the desired unprotected peptide.

Check Digit Verification of cas no

The CAS Registry Mumber 16869-58-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,6 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16869-58:
(7*1)+(6*6)+(5*8)+(4*6)+(3*9)+(2*5)+(1*8)=152
152 % 10 = 2
So 16869-58-2 is a valid CAS Registry Number.
