What the digits in 125108748 mean

The first four digits, 1251, are the Federal Reserve routing symbol. The prefix 12 places the number in the 12th Federal Reserve District (San Francisco). That is also the district where the bank is headquartered. Digits five through eight, 0874, 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 9 + 7 x 6 + 21 = 90, a multiple of 10, so 125108748 is a well-formed routing number. A mistyped digit almost always breaks that sum.
