IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7600562 this registry holds 37 other vessels, whose median build year is 1977 and which range from 1976 to 1978. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1977.
Its IMO number, 7600562, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 6×6 + 0×5 + 0×4 + 5×3 + 6×2 = 112 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
