2090-82-6 Usage
Enzyme inhibitor
This water-soluble reagent (FW = 491.26 g/mol), also known as phenolphthalein diphosphate and phenolphthalein phosphate, is an alternative substrate for phosphomonoesterases (e.g., alkaline phosphatase), as is the monophosphate. Hydrolysis of the phosphate group generates free phenolphthalein which is red in alkaline conditions. Target(s): inositol 1,4,5-trisphosphate receptors, weakly inhibited; phosphoprotein phosphatase.Check Digit Verification of cas no
The CAS Registry Mumber 2090-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.Calculate Digit Verification of CAS Registry Number 2090-82:
(6*2)+(5*0)+(4*9)+(3*0)+(2*8)+(1*2)=66
66 % 10 = 6
So 2090-82-6 is a valid CAS Registry Number.
