Valyl-leucyl-arginine-4-methoxy-2-naphthylamide, also known as V-L-R-4-M-2-N, is a synthetic chemical compound that serves as a substrate for certain enzymes, particularly those involved in the degradation of proteins. valyl-leucyl-arginine-4-methoxy-2-naphthylamide is structurally designed to mimic the sequence of amino acids found in proteins, allowing it to be recognized and cleaved by specific proteases. The 4-methoxy-2-naphthylamide group attached to the peptide sequence serves as a chromophore, which changes color upon enzymatic cleavage. This property makes it a useful tool in assays for enzyme activity, as the color change can be quantified to measure the rate of enzyme action. The compound is also of interest in the field of drug development, as it can help researchers understand and modulate the activity of proteolytic enzymes, which are implicated in various diseases and biological processes.

81523-92-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81523-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81523-92:
(7*8)+(6*1)+(5*5)+(4*2)+(3*3)+(2*9)+(1*2)=124
124 % 10 = 4
So 81523-92-4 is a valid CAS Registry Number.
