Assuming every product was initially in a quantity of 50, quite a round assumption we'll getting a sum of 157,209$ which is 10,320 higher than the sum the page is saying.
My data and calculations:

The easy number theory for a number 9 as far as i can tell is that every product ends up in 9 so an odd number of products must have been choosen if the sum also ends in 9. every even power of 9 ends in 1, odd ends with a 9.
