Alert level G
FORMU01_ALERT_1_G  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:   C2 H8 Ag1 As1 F6 N2
            Atom count from _chemical_formula_moiety:C2 H8 Ag1 As1 F1 N1
