The chemical "D-Arg-D-Pro-D-Pro-Gly-D-Phe-D-Ser-D-Pro-D-Phe-D-Arg-OH" is a cyclic nonapeptide, which means it is a peptide consisting of nine amino acids. This specific sequence is characterized by the presence of D-amino acids, which are the non-natural, or "D" stereoisomers of the more common L-amino acids found in proteins. The sequence includes D-arginine (D-Arg), D-proline (D-Pro), glycine (Gly), D-phenylalanine (D-Phe), D-serine (D-Ser), and ends with a hydroxyl group (OH). This particular arrangement of amino acids is not found in naturally occurring proteins and is likely synthesized for specific biological or pharmaceutical applications, such as in the development of drugs that target certain receptors or pathways. The cyclic nature of the peptide suggests it may have a stable, three-dimensional structure that is important for its function.
The CAS Registry Mumber 634-56-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 4 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 634-56: (5*6)+(4*3)+(3*4)+(2*5)+(1*6)=70 70 % 10 = 0 So 634-56-0 is a valid CAS Registry Number.
