We have corrected the typo in the DEA Number algorithm. Now when any pharmacy, practioner or health care provider wants to check it it will read much better. ]]>

Correct formula should read:

* Add together the first, third and fifth digits

* Add together the second, fourth and sixth digits and multiply the sum by 2

* Add the above 2 numbers

* The last digit (the ones value) of this last sum is used as the seventh digit in the DEA number
