"Z(OMe)-Ser-Tyr-Ser-Met-OMe" is a peptide sequence consisting of five amino acids: Z(OMe), Ser, Tyr, Ser, and Met, with OMe groups attached to the terminal ends. Z(OMe) represents a protected form of the amino acid methionine, where the sulfur atom is blocked by a benzyl group (Z) and a methoxy group (OMe), preventing unwanted side reactions during peptide synthesis. Ser stands for serine, an amino acid with a hydroxyl group, while Tyr is tyrosine, which contains a phenolic hydroxyl group. The sequence also includes another serine and methionine, an amino acid with a sulfur-containing side chain. The OMe group at the C-terminus protects the peptide from degradation and aids in its synthesis. This specific sequence may have potential applications in pharmaceuticals, as it could be part of a larger peptide or protein with biological activity, or it could be used in research to study peptide-protein interactions.
The CAS Registry Mumber 83283-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,8 and 3 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 83283-41: (7*8)+(6*3)+(5*2)+(4*8)+(3*3)+(2*4)+(1*1)=134 134 % 10 = 4 So 83283-41-4 is a valid CAS Registry Number.
