"Z-Gly-(C2H4CN)Gly-Gly-OTMB" is a synthetic peptide consisting of four amino acids: two glycine (Gly) residues, one cyanoacetic acid (C2H4CN) residue, and one ortho-toluidinylnaphthalenesulfonamide (OTMB) group. The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence is designed for various applications in biochemistry and molecular biology, such as fluorescent labeling, enzyme substrates, or as a component in drug design. The OTMB group serves as a chromophore, providing a strong fluorescence signal upon excitation, which can be utilized for detection and quantification purposes in various assays. The cyanoacetic acid residue introduces a cyano group into the peptide, which can potentially influence the peptide's reactivity or interaction with other molecules. Overall, this peptide is a specialized construct with potential applications in research and diagnostics.
The CAS Registry Mumber 33096-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,9 and 6 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 33096-34: (7*3)+(6*3)+(5*0)+(4*9)+(3*6)+(2*3)+(1*4)=103 103 % 10 = 3 So 33096-34-3 is a valid CAS Registry Number.
