    instructions for Luhn algorithm have a typo near the word “sunlight.”

    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

    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.
