108321-15-9 Usage
General Description
Phenolphthalein monophosphate disodium salt is a chemical compound commonly used as a sensitive and selective indicator for the detection of alkaline phosphatase in biochemical studies. It is a water-soluble, pink to red crystalline powder that is often employed in enzyme-linked immunosorbent assays (ELISA) and other biochemical assays for the rapid and accurate measurement of alkaline phosphatase activity. As a substrate for this enzyme, phenolphthalein monophosphate disodium salt undergoes dephosphorylation, resulting in the release of phenolphthalein, which produces a colorimetric change in the reaction mixture. Phenolphthalein monophosphate disodium salt is widely utilized in various research and diagnostic applications, including the determination of alkaline phosphatase levels in biological samples and the screening of enzyme inhibitors.
Check Digit Verification of cas no
The CAS Registry Mumber 108321-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,3,2 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 108321-15:
(8*1)+(7*0)+(6*8)+(5*3)+(4*2)+(3*1)+(2*1)+(1*5)=89
89 % 10 = 9
So 108321-15-9 is a valid CAS Registry Number.
