Question 4 Part 1 The checksum letter of a 7-digits number is calculated as such: d= [(i iz i3 i4 is is in). (2765 4 3 2 )] mod 11 = ( 21, +7i2 + 6i3 + 5i4 + 4is + 3i6 +27) mod 11 Where is is the l* to last of the 7 digits of the 7-digits number and (2,7,6,5,4,3,2) are the weights. The checksum is a letter which corresponds to the number d as shown in the look-up table below + 10 9 8 7 OD 6 5 LO 4 3 2 1 0 d Checksum letter A B с D E E F G H 1 Z J Question 4a Define a function that meets the following specifications.
