N-Benzyloxycarbonyl-β-cyano-L-alanin-(N-benzyl-amid), also known as Z-β-CN-L-Ala-NBzl, is a complex organic compound with the chemical formula C19H20N4O3. It is a derivative of the amino acid L-alanine, featuring a benzyloxycarbonyl (Z) protecting group on the N-terminus, a cyano group at the β-position, and a benzylamide group on the side chain. N-Benzyloxycarbonyl-β-cyano-L-alanin-(N-benzyl-amid) is commonly used in peptide synthesis as a building block, particularly in the construction of peptide sequences that require the incorporation of β-cyanoalanine residues. The protecting groups ensure that the amino acid can be selectively incorporated into the peptide chain without unwanted side reactions, and they are later removed under specific conditions to yield the desired peptide product.
The CAS Registry Mumber 4801-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,0 and 1 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4801-78: (6*4)+(5*8)+(4*0)+(3*1)+(2*7)+(1*8)=89 89 % 10 = 9 So 4801-78-9 is a valid CAS Registry Number.
