Z-Lys(Z)-Cys(Bzl) is a tripeptide composed of three amino acids: Z-protected lysine (Lys), cysteine (Cys) with a benzyl (Bzl) group, and an additional Z-protected lysine. The Z group (benzyloxycarbonyl) is a protecting group used in peptide synthesis to prevent unwanted side reactions, such as peptide bond formation, during the synthesis process. The benzyl group in Cys(Bzl) serves a similar purpose, protecting the thiol group of cysteine. This specific sequence and protection scheme are crucial for the controlled synthesis of larger peptides and proteins, as it allows for the stepwise assembly of the peptide chain while maintaining the integrity of the individual amino acids. The use of protecting groups is a common strategy in organic chemistry and peptide synthesis to ensure that reactions proceed in a predictable and controlled manner.

16869-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16869-57-1 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 7 respectively.Calculate Digit Verification of CAS Registry Number 16869-57:
(7*1)+(6*6)+(5*8)+(4*6)+(3*9)+(2*5)+(1*7)=151
151 % 10 = 1
So 16869-57-1 is a valid CAS Registry Number.
