(4) FEIN/Sequence Number Check Digit Formula
The check digit is figured from the following calculations.
Step 1: Beginning at the left most digit, multiply each digit of the FEIN alternating by 2 and then 1. 
     EXAMPLE: FEIN Sequence Number = 5 7 4 5 4 2 4 9 6 0 0 0  
             5       7       4      5        4       2       4      9           6     0          0     0
        X    2       1       2      1        2       1       2      1           2     1          2     1
          =   10     7       8      5        8       2       8      9   12            0          0     0
Step 2: Add any two-digit number in the products together to obtain one digit.  (10 = 1 + 0 = 1) (12 = 1 + 2 =  )3
Step 3: Add the Step 1 products together substituting the one-digit number found in Step 2 for the two-digit number. 
     1 + 7 + 8 + 5 + 8 + 2 + 8 + 9 +  3+ 0 + 0 + 0 = 51.  
Step 4: Determine the unit (ones) position of the result of Step 3. The unit position of 51 is 1.
Step 5: If the result of Step 4 is zero, zero is the check digit. If the result of Step 4 is not zero, subtract the unit 
     position from 10.  In this example, 1 is the result of Step 4. 10 - 1 = 9. 9 is the check digit.

(10) Scan Line Placement and Contents 
The scan line must be centered horizontally on the page (the center of the scan line must be at 4.25 inches) and 
must fall between .25 and .375 inches from the bottom edge of the form. There must be only the scan line in the 
bottom .5 inch of the form. 
Contents: The scan line contains 39 positions as described below. The font for the scan line is “OCR-A Std”, size 10.
   Positions within the scan line:
     1 - 5  Voucher Number is always 11208

Form Code/Liability Period Check Digit Formula
The check digit is figured from the following calculations.
EXAMPLE: Form code/Liability Period = 1 1 2 0 8 1 2 2 3
Step 1:    Beginning at the left most digit, multiply the left most digit by 10, the next digit by 9, the next by 8 and so    
        on, until all digits have a total.
                 1       1        2       0   8     1                          2 2 3
      X          10      9        8       7   6     5                          4 3 2
      =          10      9        16      0   48    5                          8 6 6
Step 2:     Add the products together. 10 + 9 + 16 + 0 + 48 + 5 + 8 + 6 + 6 = 108
Step 3:     Divide the sum by 11. Determine the remainder. 108 divided by 11 = 9 with a remainder of 9.
Step 4:     If the remainder is 0 or 1, the remainder is the check digit. If the remainder is greater than 1, subtract the   
        remainder from 11 to obtain the check digit. 11 - 9 = 2.  2 is the check digit for this example.

(11) 1-D Barcode
1-D Barcode font is “Free 3 of 9 Extended”, size 30 pt (height around 5/16 inch). Leave at least 1/4 inch quiet zone 
(white space) around the barcode. Reproduce the exact barcode shown on the voucher. The content of the barcode 
is: *62812231V*

Important: Electronic payments are required if the taxpayer’s previous year’s annual liability was $20,000 or
