"Z(OMe)-Val-His-Asn-Phe-NH2" is a peptide sequence consisting of six amino acids: Z(OMe), Val, His, Asn, Phe, and NH2. Z(OMe) represents a protected amino acid, where the Z group is a benzyloxycarbonyl (Cbz) protecting group, and the OMe group is a methoxyethyl (MEO2C) protecting group. Val is valine, His is histidine, Asn is asparagine, and Phe is phenylalanine. The NH2 at the end indicates the presence of a primary amine group. This peptide sequence is likely used in pharmaceutical or chemical research, as the protecting groups are commonly used to prevent unwanted side reactions during peptide synthesis. The sequence may have specific biological activity or be part of a larger peptide or protein structure.
The CAS Registry Mumber 83069-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,6 and 9 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 83069-69: (7*8)+(6*3)+(5*0)+(4*6)+(3*9)+(2*6)+(1*9)=146 146 % 10 = 6 So 83069-69-6 is a valid CAS Registry Number.
