IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5172705 this registry holds 13 other vessels, whose median build year is 1952 and which range from 1907 to 1963. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1963.

Its IMO number, 5172705, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 1×6 + 7×5 + 2×4 + 7×3 + 0×2 = 105 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
