IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9128532 this registry holds 62 other vessels, whose median build year is 1996 and which range from 1995 to 1999. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1999.
Its IMO number, 9128532, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 1×6 + 2×5 + 8×4 + 5×3 + 3×2 = 132 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
