I'm afraid that what you are asking is not actually possible. There isn't a canonical/absolute way of numbering a chemical. That is to say, atom numbering is not a property of the molecule, it is an attribute of the nomeclature system and how it is applied. Take for example: http://www.chemspider.com/Chemical-Structure.13835772.html.
Here, the name 2-Methylphenol uses the position of the (phenolic) hydroxy group as the intial reference point (i.e. carbon 1) so the methyl group is in the 2-position.
But in the name 2-hydroxytoluene, the numbering is based on the methyl group being the point of reference (i.e. carbon 1) and the hydroxy group is in the 2 position.
It is for this reason that in a ChemSpider record we make the chemical structure the basis for the record and then link data and names to that.
