"O-(N-Benzyloxycarbonyl-L-leucyl)-L-α-hydroxy-isovaleriansaeure-tert.-butylester" is a complex organic compound with the chemical formula C22H35NO5. It is a derivative of L-α-hydroxyisovaleric acid, featuring a tert-butyl ester group and an N-benzyloxycarbonyl-L-leucine moiety. O-(N-Benzyloxycarbonyl-L-leucyl)-L-α-hydroxy-isovaleriansaeure-tert.-butylester is often used in peptide synthesis as a protecting group for the α-hydroxy acid functionality, which helps prevent unwanted side reactions during the assembly of peptide sequences. The N-benzyloxycarbonyl (Z) group is a common protecting group for the amino group of amino acids, while the tert-butyl ester (t-Bu) group protects the carboxylic acid group. The compound's structure allows for controlled deprotection steps, which are crucial for the successful synthesis of peptides and other biomolecules.

1803-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1803-68-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.Calculate Digit Verification of CAS Registry Number 1803-68:
(6*1)+(5*8)+(4*0)+(3*3)+(2*6)+(1*8)=75
75 % 10 = 5
So 1803-68-5 is a valid CAS Registry Number.
