Z-L-Leu-D-Phe-L-Pro-L-Val-OMe is a peptide compound consisting of five amino acids: L-Leucine (L-Leu), D-Phenylalanine (D-Phe), L-Proline (L-Pro), and L-Valine (L-Val), with a methoxy group (OMe) attached to the N-terminus. The sequence is protected by a Z-group (benzyloxycarbonyl) at the N-terminus, which is a common protecting group used in peptide synthesis to prevent unwanted side reactions. This specific peptide sequence is of interest in the field of medicinal chemistry, particularly in the development of potential therapeutic agents, as it may exhibit unique biological activities due to its non-standard D-amino acid incorporation and the presence of the Z-group.
The CAS Registry Mumber 75319-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,3,1 and 9 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 75319-54: (7*7)+(6*5)+(5*3)+(4*1)+(3*9)+(2*5)+(1*4)=139 139 % 10 = 9 So 75319-54-9 is a valid CAS Registry Number.
