N-[(Benzyloxy)carbonyl]-L-leucine 2,4,5-trichlorophenyl ester is a complex organic compound with the chemical formula C21H20Cl3NO4. It is a derivative of L-leucine, an essential amino acid, and is characterized by the presence of a benzyloxycarbonyl (Cbz) protecting group and a 2,4,5-trichlorophenyl ester moiety. N-[(Benzyloxy)carbonyl]-L-leucine 2,4,5-trichlorophenyl ester is primarily used in peptide synthesis as a protected amino acid building block, where the Cbz group serves to protect the amino group during the coupling reactions, and the 2,4,5-trichlorophenyl ester group protects the carboxylic acid function. The trichlorophenyl ester is more acid-labile than other esters, which allows for selective deprotection under mild acidic conditions, making it a valuable tool in the synthesis of complex peptides and proteins.

7646-49-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7646-49-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7646-49:
(6*7)+(5*6)+(4*4)+(3*6)+(2*4)+(1*9)=123
123 % 10 = 3
So 7646-49-3 is a valid CAS Registry Number.
