To calculate the verification values you need the following data:
Enter the 16 or 19 digits card number:
Enter the 4 digit Expiry Date YYMM(EX: 2312):
Enter the 32 hex digits CVV Encryption Key(MDK):
Service code (used for CVV/CVC only):
Application Transaction Counter ATC(used for dCVV only):
Documentation - How to calculate CVV - Algorythm
Step 1. Ensure a 2-part 16 byte key. That is 32 hex characters. We will call this "Key"
Step 2. Ensure 16 or 19 digits PAN Card number
Step 3. Ensure 4 characters of Expiration Date
Step 4. Ensure 3 characters of Service Code
Step 5. Concatenate PAN, Expiry date, Service Code
Step 6. Fill with zeroes to the right until you have 32 characters. We will call this "Data"
Step 7. Encrypt (DES) the first half of the data with the first half of the key
Step 8. XOR the result with the second half of Data.
Step 9. Encrypt (DES) the result with the first half of the Key.
Step 10. Decrypt the result with the second half of the key.
Step 11. Encrypt the result with the first half of the key.
Step 12. Get only the digits(numbers) from the result; First 3 are the CVV

This article describes how the ISO8583 Converter creates an XML, SQL and CSV object from an incoming TCP/IP ISO8583 binary message, and then sends it to a HTTp host as a POST, and a Mysql database, and a flat file on disk respectively. Go to ISO8583 converter to JSON for more details and download links.
