N-Benzyloxycarbonyl-L-leucin- is a complex organic compound with the chemical formula C18H30N2O3. It is a derivative of L-leucine, an essential amino acid, and is characterized by the presence of a benzyloxycarbonyl group and a piperidino-1-yl ester moiety. N-Benzyloxycarbonyl-L-leucin- is often used in peptide synthesis as a protecting group for the carboxyl group of amino acids, which helps prevent unwanted side reactions during the formation of peptide bonds. The benzyloxycarbonyl group can be removed under acidic conditions, while the piperidino-1-yl ester provides stability and can be cleaved under mild basic conditions. Its use in peptide chemistry is crucial for the controlled synthesis of complex peptide sequences, making it a valuable tool in the field of biochemistry and pharmaceutical research.

Check Digit Verification of cas no

The CAS Registry Mumber 4091-51-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4091-51:
(6*4)+(5*0)+(4*9)+(3*1)+(2*5)+(1*1)=74
74 % 10 = 4
So 4091-51-4 is a valid CAS Registry Number.
