Z-Asn-Cys(CH2SBzl)-ONp is a synthetic peptide compound consisting of three amino acids: Asparagine (Asn), Cysteine (Cys), and a modified Asparagine (Asn) with a nitrophenyl (ONp) group. The Cysteine residue is further modified with a benzyl (Bzl) group attached to its sulfur atom. Z-Asn-Cys(CH2SBzl)-ONp is often used in peptide synthesis and protein chemistry, particularly for studying protein folding, stability, and interactions. The Z-group (benzyloxycarbonyl) is a protecting group that shields the amino group of Asn, preventing unwanted side reactions during peptide synthesis. The compound's structure and modifications make it a valuable tool for researchers in the field of biochemistry and molecular biology.
The CAS Registry Mumber 4801-53-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,0 and 1 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4801-53: (6*4)+(5*8)+(4*0)+(3*1)+(2*5)+(1*3)=80 80 % 10 = 0 So 4801-53-0 is a valid CAS Registry Number.
