This is because a value of one multiplied by 89 (sum of weights) is 89, and 89 divided by 11 is 8 with remainder 1/11; thus 1 is the check digit.
And 89 divided by 11 is 8 with the remainder being the fraction "1 over 11," thus 1 is the check digit. This is because a value of one, multiplied against 89 (sum of weights), is still 89.
