That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2009.
Its IMO number, 9386122, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 3×6 + 8×5 + 6×4 + 1×3 + 2×2 = 152 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
