"Z-Phe-ΔZPhe-OH" is a synthetic peptide consisting of two amino acid residues, phenylalanine (Phe) and ΔZPhe, which is a derivative of phenylalanine with a double bond between the α and β carbons. The "Z" prefix indicates that the peptide is protected with a benzyloxycarbonyl (Cbz) group, a common protecting group in peptide synthesis that prevents unwanted side reactions. This specific peptide is of interest in the field of organic chemistry and peptide synthesis, particularly for studying the effects of double bonds on peptide conformation and reactivity. It may also have applications in the development of new pharmaceuticals or as a research tool in understanding protein structure and function.

Check Digit Verification of cas no

The CAS Registry Mumber 91177-54-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91177-54:
(7*9)+(6*1)+(5*1)+(4*7)+(3*7)+(2*5)+(1*4)=137
137 % 10 = 7
So 91177-54-7 is a valid CAS Registry Number.
