Sorry harish_256 it was a bit of a joke fallen flat rather than pedantry. What I meant was that C1289H2051N343O375S8 can potentially refer to several thousand compounds. The name <insert long name here> is still not completely specific and may referer to several dozen or even more compounds.
This is because there are a number of atoms in the compound which, due to thier configuration have two different forms which are mirror images of one another. These atoms are known as chiral centres. Each chiral centre can give rise to two different compounds.
I hope that explains what I was talking about.
