Z-Gly-D-Phe-NH-NH2 is a synthetic peptide consisting of three amino acids: Z-protected glycine (Z-Gly), D-phenylalanine (D-Phe), and a terminal amino group (NH-NH2). The Z-group (benzyloxycarbonyl) is a protecting group used in peptide synthesis to prevent unwanted side reactions. This specific sequence is known for its potential role in the development of certain pharmaceuticals, particularly in the field of pain management and as a precursor in the synthesis of more complex peptide drugs. The D-configuration of phenylalanine indicates that it is the non-natural, or mirror-image, isomer of the naturally occurring L-phenylalanine, which can be important for the peptide's biological activity and stability. The terminal amino group suggests that this peptide could be further elongated or used in conjugation reactions. Overall, Z-Gly-D-Phe-NH-NH2 is a building block in the synthesis of more complex biologically active peptides.
The CAS Registry Mumber 5183-94-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 3 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5183-94: (6*5)+(5*1)+(4*8)+(3*3)+(2*9)+(1*4)=98 98 % 10 = 8 So 5183-94-8 is a valid CAS Registry Number.
