"Z-Phe-Ser-Pro-Phe-Arg(NO2)-OMe" is a peptide compound consisting of six amino acids: phenylalanine (Phe), serine (Ser), proline (Pro), another phenylalanine (Phe), arginine with a nitro group (Arg(NO2)), and methoxy group (OMe). The "Z" prefix indicates that the peptide is protected with a carbobenzyloxy (Cbz) group, which is a common protecting group used in peptide synthesis to prevent unwanted side reactions. This specific sequence of amino acids forms a peptide chain with a nitro group on the arginine residue, which may confer unique chemical or biological properties. The compound is of interest in the fields of chemistry and biochemistry, particularly in the study of peptide synthesis, structure, and function.
The CAS Registry Mumber 16152-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,5 and 2 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 16152-76: (7*1)+(6*6)+(5*1)+(4*5)+(3*2)+(2*7)+(1*6)=94 94 % 10 = 4 So 16152-76-4 is a valid CAS Registry Number.
