The chemical compound "C13H20HgO3" is an organic mercury compound with the molecular formula indicating that it contains 13 carbon atoms, 20 hydrogen atoms, 1 mercury atom, and 3 oxygen atoms. C13H20HgO3 is likely to be a derivative of a phenol or a carboxylic acid, given the presence of oxygen atoms, which could be part of hydroxyl or carboxyl groups. The mercury atom suggests that it may have potential applications in areas where organomercury compounds are used, such as in certain types of fungicides or as a reagent in organic synthesis. However, due to the toxicity of mercury and its compounds, especially organic ones, this substance would be of concern from an environmental and health perspective, and its use would be strictly regulated.
The CAS Registry Mumber 5202-44-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 2 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5202-44: (6*5)+(5*2)+(4*0)+(3*2)+(2*4)+(1*4)=58 58 % 10 = 8 So 5202-44-8 is a valid CAS Registry Number.
