N-Benzyloxycarbonyl-γ-L-glutamyl-S-benzyl-L-cystein, also known as Z-Glu-SBzl-Cys, is a peptide derivative that consists of three amino acids: N-benzyloxycarbonyl-protected glutamic acid (Z-Glu), cysteine with a benzyl protecting group (S-benzyl-Cys), and a γ-peptide bond. N-Benzyloxycarbonyl-γ-L-glutamyl-S-benzyl-L-cystein is widely used in peptide synthesis as a building block, particularly in the formation of cyclic peptides and proteins. The benzyl protecting groups are crucial for preventing unwanted side reactions, such as oxidation or unwanted coupling, during the synthesis process. Once the desired peptide structure is achieved, the protecting groups can be removed to reveal the final product. Z-Glu-SBzl-Cys is an essential component in the development of pharmaceuticals, bioactive peptides, and other peptide-based compounds due to its stability and reactivity.
The CAS Registry Mumber 3057-72-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 7 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3057-72: (6*3)+(5*0)+(4*5)+(3*7)+(2*7)+(1*2)=75 75 % 10 = 5 So 3057-72-5 is a valid CAS Registry Number.
