N-Benzyloxycarbonyl-D-asparaginsaeure-<α-(2,4,5-trichlor-phenyl)-β-benzyl-ester> is a complex organic compound with the chemical formula C27H22Cl3N2O6. It is a derivative of D-asparagine, an amino acid, with a benzyloxycarbonyl group attached to the nitrogen atom and a 2,4,5-trichlorophenyl group connected to the α-carbon. Additionally, a benzyl group is esterified to the β-carbon. N-Benzyloxycarbonyl-D-asparaginsaeure-<α-(2,4,5-trichlor-phenyl)-β-benzyl-ester> is often used in peptide synthesis as a protecting group for aspartic acid residues, which helps prevent unwanted side reactions during the formation of peptide bonds. The presence of the trichlorophenyl group provides a unique chemical handle for further functionalization or purification steps in synthetic chemistry.
The CAS Registry Mumber 5289-01-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 9 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5289-01: (6*5)+(5*2)+(4*8)+(3*9)+(2*0)+(1*1)=100 100 % 10 = 0 So 5289-01-0 is a valid CAS Registry Number.
