1. First add all the numbers in the ODD positions.
i.e.,
0+2+4+6+8+0
=
20
2. Multiple the result of step 1 by 3.
i.e.,
20
x
3
=
60
3. Add up all the numbers in the EVEN positions.
i.e.,
1+3+5+7+9
=
25
4. Add the result of step 2 to that of step 3.
i.e.,
60
+
25
=
85
5.
Subtract
the
result
of
step
4
from the next highest increment of 10.
i.e., 90 – 85 = 5
6. The correct Modulo 10 check digit for the 11 digit string “01234567890”
is 5.
