Z-Ser-Ser-Lys(Boc)-NHNH2 is a peptide compound consisting of four amino acids: Z-protected serine (Ser), serine (Ser), and Boc-protected lysine (Lys), with a free amine group at the C-terminus. The Z group (benzyloxycarbonyl) and Boc group (tert-butoxycarbonyl) are protecting groups used to prevent unwanted side reactions during peptide synthesis. This specific sequence of amino acids is of interest in the field of peptide chemistry, as it can be used to study protein-protein interactions, develop new drugs, or understand the structure and function of proteins. The presence of the Boc group on lysine indicates that this peptide is synthesized using a Boc-based strategy, which is one of the two main strategies for peptide synthesis, the other being the Fmoc (9-fluorenylmethoxycarbonyl) strategy.
The CAS Registry Mumber 73535-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,3 and 5 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 73535-41: (7*7)+(6*3)+(5*5)+(4*3)+(3*5)+(2*4)+(1*1)=128 128 % 10 = 8 So 73535-41-8 is a valid CAS Registry Number.
