N-Benzyloxycarbonyl-α-tert.-butyl-L-glutamyl-β-alanin-pentachlorphenylester is a complex organic compound with the molecular formula C26H26Cl5N2O6. It is a derivative of glutamic acid, an amino acid, and is characterized by the presence of a benzyloxycarbonyl group, a tert-butyl group, and a β-alanine residue. N-Benzyloxycarbonyl-α-tert.-butyl-L-glutamyl-β-alanin-pentachlorphenylester is often used in peptide synthesis as a protecting group to prevent unwanted side reactions during the formation of peptide bonds. The pentachlorophenyl ester group serves as a leaving group, facilitating the coupling reaction in peptide synthesis. Its chemical structure and properties make it a valuable tool in the field of organic chemistry, particularly in the synthesis of complex peptide sequences.
The CAS Registry Mumber 5105-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 5 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5105-71: (6*5)+(5*1)+(4*0)+(3*5)+(2*7)+(1*1)=65 65 % 10 = 5 So 5105-71-5 is a valid CAS Registry Number.
