Price not adjusted for split

I would like to compute the price of a given stock if no split had ever occurred.

For instance, XOM had 5 splits over time, each one was 2 for 1. Since the stock price gets divided by 2 every time there is a split, we need to reverse that process and multiply by 2 for each split, so:

2*2*2*2*2=2^5=32

XOM trades at $88.75 right now, so unadjusted for the split we would have: $88.75*32=$2840

Thanks for your help,
