The given chemical equation represents the formation of a complex compound involving uranium(VI), nitrate, and a ligand with the formula C13H20N3O. The equation can be broken down as follows: UO2(2+) represents the uranium(VI) ion, NO3(1-) is the nitrate ion, and C13H20N3O(1-) is the ligand. The product, UO2C13H20N3O(NO3), indicates that the uranium(VI) ion has formed a complex with the ligand, and a nitrate ion is also associated with the complex. This complex formation is a common phenomenon in coordination chemistry, where a central metal ion (in this case, uranium) is surrounded by one or more ligands, which can be neutral molecules or anions. The nitrate ion in this context may either be part of the coordination sphere or act as a counterion, depending on the specific structure of the complex.
The CAS Registry Mumber 57458-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,5 and 8 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 57458-32: (7*5)+(6*7)+(5*4)+(4*5)+(3*8)+(2*3)+(1*2)=149 149 % 10 = 9 So 57458-32-9 is a valid CAS Registry Number.
