Guide to Calculating Austrian PZN Check Digit

  1. Start with the 6-digit base PZN code.
  2. Multiply each digit by its corresponding weight:
    • 1st digit × 2
    • 2nd digit × 3
    • 3rd digit × 4
    • 4th digit × 5
    • 5th digit × 6
    • 6th digit × 7
  3. Sum up all the products from step 2.
  4. Divide the sum by 11 and take the remainder (Modulo 11).
  5. The remainder is the check digit.
  6. If the check digit is 10, the PZN is not valid and should not be used.
  7. Append the check digit to the original 6-digit code to form the complete 7-digit PZN.
