"Z-Arg(Mts)-Pro-Val-Lys(Z)-Val-Tyr-OMe" is a peptide sequence consisting of eight amino acids. It is a synthetic compound with a specific arrangement of amino acids, each playing a crucial role in the overall structure and function of the peptide. The sequence starts with Z-Arg(Mts), where "Z" is a protecting group for the carboxyl group, and "Mts" is a protecting group for the guanidino group of arginine. This is followed by Pro (proline), Val (valine), Lys(Z) with another "Z" protecting group on the epsilon amino group of lysine, another Val (valine), Tyr (tyrosine), and ends with OMe, which indicates a methoxy group attached to the carboxyl terminus. This particular sequence is of interest in peptide chemistry and may have applications in drug development, as the specific arrangement of amino acids can influence biological activity. The protecting groups are used during synthesis to prevent unwanted reactions and are removed later to reveal the active peptide.
The CAS Registry Mumber 84860-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,6 and 0 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 84860-08: (7*8)+(6*4)+(5*8)+(4*6)+(3*0)+(2*0)+(1*8)=152 152 % 10 = 2 So 84860-08-2 is a valid CAS Registry Number.
