"UO2(tropolonate)2*tropolone" is a complex chemical compound consisting of uranium dioxide (UO2), tropolonate ions, and tropolone molecules. In UO2(tropolonate)2*tropolone, uranium dioxide acts as the central metal ion, while tropolonate ions (C7H5O3-) and tropolone molecules (C7H6O2) serve as ligands, coordinating with the uranium ion to form a stable complex. Tropolonate is a derivative of tropolone, featuring an additional carboxylate group that allows it to bind more effectively to the uranium center. UO2(tropolonate)2*tropolone is of interest in the field of inorganic chemistry, particularly in the study of actinide complexes, and may have applications in nuclear chemistry and materials science.
The CAS Registry Mumber 21157-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 21157-59: (7*2)+(6*1)+(5*1)+(4*5)+(3*7)+(2*5)+(1*9)=85 85 % 10 = 5 So 21157-59-5 is a valid CAS Registry Number.
