"Z-Phe-Val-Pro-Ile-Phe-Thr(Bzl)-Tyr(Bzl)-Gly-OMe" is a peptide sequence consisting of ten amino acids. It is a synthetic compound with a specific arrangement of amino acids, each denoted by its three-letter code. The sequence starts with phenylalanine (Phe), followed by valine (Val), proline (Pro), isoleucine (Ile), another phenylalanine, threonine with a benzyl group (Thr(Bzl)), tyrosine with a benzyl group (Tyr(Bzl)), glycine (Gly), and ends with a methoxy group (OMe). The benzyl groups are protecting groups used in peptide synthesis to prevent unwanted side reactions. This particular sequence is not a naturally occurring peptide but is likely used in research or pharmaceutical development for studying protein interactions or as a potential drug candidate.
The CAS Registry Mumber 82263-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,6 and 3 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 82263-40: (7*8)+(6*2)+(5*2)+(4*6)+(3*3)+(2*4)+(1*0)=119 119 % 10 = 9 So 82263-40-9 is a valid CAS Registry Number.
