General Description
4-Methylumbelliferyl nonanoate is a chemical compound commonly used in biochemical assays to detect the activity of lipase enzymes. It is a synthetic substrate consisting of a nonanoate ester of 4-methylumbelliferone, which emits a fluorescent signal upon hydrolysis by lipase enzymes. The fluorescence emitted upon cleavage of the nonanoate ester can be quantitatively measured and used to determine the activity of the lipase enzyme in various biological samples. 4-METHYLUMBELLIFERYL NONANOATE has been widely utilized in research and diagnostic laboratories for studying lipid metabolism and investigating diseases related to lipase dysfunction, such as pancreatic disorders and obesity. Additionally, 4-methylumbelliferyl nonanoate is also employed in the screening of potential lipase inhibitors for drug development and pharmaceutical research.
Check Digit Verification of cas no
The CAS Registry Mumber 18319-93-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,1 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18319-93:
(7*1)+(6*8)+(5*3)+(4*1)+(3*9)+(2*9)+(1*3)=122
122 % 10 = 2
So 18319-93-2 is a valid CAS Registry Number.
