"Z(OMe)-His-Asn-Leu-Gly-OMe" is a peptide sequence consisting of five amino acids: Z(OMe), His, Asn, Leu, and Gly, with OMe groups at both the N-terminus and C-terminus. Z(OMe) represents a protected histidine residue, where the imidazole ring is modified with a benzyl group (Z) and a methoxy group (OMe), preventing unwanted side reactions during peptide synthesis. His stands for histidine, an amino acid with a basic side chain containing an imidazole ring. Asn is asparagine, a polar amino acid with an amide side chain. Leu is leucine, a nonpolar amino acid with an aliphatic side chain. Gly is glycine, the simplest amino acid with a single hydrogen atom as its side chain. The OMe group at the C-terminus serves as a protecting group and also aids in the solubility of the peptide. This specific sequence may have potential applications in pharmaceuticals, biotechnology, or as a building block for larger peptide structures.
The CAS Registry Mumber 83069-37-8 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, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 83069-37: (7*8)+(6*3)+(5*0)+(4*6)+(3*9)+(2*3)+(1*7)=138 138 % 10 = 8 So 83069-37-8 is a valid CAS Registry Number.
