Description
Checks whether the formula is chemically valid, i.e. has no zero-count or
negative-count elements.
Usage
1
Arguments
formula
A molecular formula in string or list representation
("C6H6" or list(C=6,H=6)).
Details
The check is only meant to identify formulas which have negative elements,
which can arise from the subtraction of adducts. It is not a
high-level formula "validity" check like e.g. the Rcdk function
isvalid.formula which uses the nitrogen rule or a DBE rule.
