What the digits in 101105118 mean
The first four digits, 1011, are the Federal Reserve routing symbol. The prefix 10 places the number in the 10th Federal Reserve District (Kansas City). That is also the district where the bank is headquartered. Digits five through eight, 0511, identify the institution within its Federal Reserve district. The last digit, 8, is a check digit. Weighting the digits 3, 7 and 1 in turn gives 3 x 3 + 7 x 1 + 14 = 30, a multiple of 10, so 101105118 is a well-formed routing number. A mistyped digit almost always breaks that sum.
