The given chemical formula represents a complex compound consisting of a tetracationic ammonium ion, [(C4H9)4N]4+, coordinated to a technetium(V) oxide center, TcO2, which is further chelated by a bidentate ligand, OC6H4CHNC6H4O, and a water molecule, H2O. The overall formula is [(C4H9)4N[TcO2(OC6H4CHNC6H4O)(H2O)]]. This complex is an example of a coordination compound where the central metal ion, technetium, is surrounded by various ligands, forming a stable structure. The presence of the hydroxide ion, H2O(1-), indicates that the complex carries a negative charge, which is balanced by the positive charge of the ammonium ion. (C4H9)4N(1+)*TcO2(OC6H4CHNC6H4O)H2O(1-)=(C4H9)4N[TcO2(OC6H4CHNC6H4O)(H2O)] could be relevant in the field of radiopharmaceuticals, where technetium-99m is a commonly used isotope for imaging due to its favorable nuclear properties.
The CAS Registry Mumber 89554-14-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,5 and 4 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 89554-14: (7*8)+(6*9)+(5*5)+(4*5)+(3*4)+(2*1)+(1*4)=173 173 % 10 = 3 So 89554-14-3 is a valid CAS Registry Number.
