Validating the DEA Number

---

In the U.S., the DEA number is a federally authorized number for physicians at a specific address.

In Siebel ePharma Handheld, the DEA number is stored at the address level for each physician. Siebel ePharma Handheld can confirm that a valid DEA number is populated at the selected address for a professional call. Depending on how your Siebel ePharma Handheld application is configured, the valid DEA number check can be performed at the time of entering the DEA number, upon launching the Siebel Signature Capture display, or both.

If:

The product dropped is a controlled substance and
The user property "Validate Address DEA Number" or "Validate Signature DEA Number" is true

then Siebel ePharma Handheld checks the validity of the DEA number by executing the algorithm described in Table 12.

Table 12.  The DEA Number Checksum Algorithm

Step	Algorithm	Example
1	The first two characters must be uppercase letters.	BB1388568
2	Sum the first, third, and fifth digits.	1 + 8 + 5 = 14
3	Sum the second, fourth, and sixth digits.	3 + 8 + 6= 17
4	Double the number obtained in step 3.	2 × 17 = 34
5	Sum the numbers from steps 2 and 4.	14 + 34 = 48
6	If the last digit of the DEA number is the same as the last digit of the number obtained in step 5, the DEA number is considered valid.	The last digit of BB1388568 and 48 is the same, "8". This checksum indicates that the DEA number is valid.
