"Z(OMe)-Asp(O-tBu)-ONP" is a complex chemical compound consisting of three main components: Z(OMe), Asp(O-tBu), and ONP. Z(OMe) refers to a benzyloxycarbonyl (Z) group with a methoxy (OMe) substitution, which is commonly used in peptide synthesis to protect the amino group. Asp(O-tBu) denotes an aspartic acid residue with a tert-butyl (tBu) ester protecting group on its carboxylic acid side chain, which is crucial for maintaining the integrity of the peptide during synthesis. ONP stands for ortho-nitrophenol, a chromogenic compound used as a leaving group in peptide synthesis, facilitating the coupling of amino acids. Z(OMe)-Asp(O-tBu)-ONP is typically employed in the solid-phase peptide synthesis (SPPS) process, where it aids in the stepwise assembly of peptide chains by providing a detectable color change upon reaction, thus serving as an indicator of successful peptide bond formation.
The CAS Registry Mumber 78075-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,7 and 5 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 78075-47: (7*7)+(6*8)+(5*0)+(4*7)+(3*5)+(2*4)+(1*7)=155 155 % 10 = 5 So 78075-47-5 is a valid CAS Registry Number.
