Z-Arg(NO2)-Phe-NHNHBoc is a synthetic peptide compound consisting of four amino acids: Z-protected arginine with a nitro group (Arg(NO2)), phenylalanine (Phe), and a Boc-protected amino group (NHNHBoc). The Z-group (benzyloxycarbonyl) is a protecting group used in peptide synthesis to prevent unwanted side reactions, while the Boc group (tert-butoxycarbonyl) serves a similar purpose. This specific sequence of amino acids is of interest in the field of peptide chemistry, potentially for studying protein-protein interactions, drug design, or as a building block in the synthesis of larger biomolecules. The nitro group on the arginine residue may also confer unique chemical or biological properties to the peptide, making it a subject of interest for researchers exploring the effects of such modifications on peptide behavior.
The CAS Registry Mumber 78578-34-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,7 and 8 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 78578-34: (7*7)+(6*8)+(5*5)+(4*7)+(3*8)+(2*3)+(1*4)=184 184 % 10 = 4 So 78578-34-4 is a valid CAS Registry Number.
