"N-(Nα,Nδ-bis-benzyloxycarbonyl-L-ornithyl)-L-leucine methyl ester" is a complex organic compound with the molecular formula C31H44N2O6. It is a derivative of L-leucine, an essential amino acid, and L-ornithine, a non-essential amino acid. The compound features a leucine residue with an Nα,Nδ-bis-benzyloxycarbonyl-L-ornithine moiety attached to its nitrogen atom. The benzyloxycarbonyl (Z) protecting groups are used to shield the amino and carboxylic acid groups during peptide synthesis, preventing unwanted side reactions. The methyl ester group at the C-terminus indicates that the compound is a methyl ester derivative, which can be used in various chemical reactions and as a building block in peptide synthesis. N-(Nα.Nδ-bis-benzyloxycarbonyl-L-ornithyl)-L-leucine methyl ester is significant in the field of organic chemistry and biochemistry, particularly in the synthesis of peptides and proteins, where the protecting groups can be selectively removed to reveal the free amino acid residues.
The CAS Registry Mumber 4818-10-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,1 and 8 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4818-10: (6*4)+(5*8)+(4*1)+(3*8)+(2*1)+(1*0)=94 94 % 10 = 4 So 4818-10-4 is a valid CAS Registry Number.
