General Notes



FORMU_01  There is a discrepancy between the atom counts in the                 
          _chemical_formula_sum and _chemical_formula_moiety. This is           
          usually due to the moiety formula being in the wrong format.          
          Atom count from _chemical_formula_sum:   C8 H20 N2 O12                
          Atom count from _chemical_formula_moiety:C5 H12 N1 O38                


 0 Alert Level A = Potentially serious problem

 0 Alert Level B = Potential problem

 2 Alert Level C = Please check
