Definition
The IMO ship identification number is made of the three letters "IMO" followed by the seven-digit number assigned to all ships by IHS Fairplay (formerly known as Lloyd's Register-Fairplay) when constructed. This is a unique seven digit number that is assigned to propelled, all passenger ships of 100 GT and above and cargo ships of 300 gross tonnage and above, upon keel laying with the exception of the following:
The integrity of an IMO number can be verified by its check digit, which is the rightmost digit. This is done by multiplying each of the leftmost six digits by a factor corresponding to their position from right to left, and adding those products together. The rightmost digit of this sum is the check digit. For example, for IMO 7654329: 7×7 + 6×6 + 5×5 + 4×4 + 3×3 + 2×2 = 139.

Famous quotes containing the word definition:
“Scientific method is the way to truth, but it affords, even in
principle, no unique definition of truth. Any so-called pragmatic
definition of truth is doomed to failure equally.”
—Willard Van Orman Quine (b. 1908)
“It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.”
—François, Duc De La Rochefoucauld (1613–1680)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
