DEA #
Definition
Here are the steps to verify a DEA number: 
Step 1: add the first, third, and fifth digits of the DEA number. 

Step 2: add the second, fourth, and sixth digits of the DEA number. 

Step 3: multiply the result of Step 2 by two. 

Step 4: add the result of Step 1 to the result of Step 3. 
Then, the last digit of this sum must be the same as the last digit of the DEA number. 

Example: DEA number AP5836727 
Step 1: 5 + 3 + 7 = 15 
Step 2: 8 + 6 + 2 = 16 
Step 3: 16 * 2 = 32 
Step 4: 15 + 32 = 47
