International Standard Music Number 3 left to right. These weighted digits are added together. The check digit is the integer between 0 and 9 that makes the sum a multiple of 10. For instance, for the item with ISMN beginning 979-0-060-11561: As 85 mod 10 = 5, the check digit is 10 - 5 = 5 and the full number is 979-0-060-11561-5. For another example, Robert Fripp's collection of Guitar Craft scores has the ISMN 979-0-9016791-7-7. Given first 12 digits 979-0-9016791-7, the ISMN algorithm evaluates which implies that the check digit is indeed 7 (because 123+7=130=13x10).

Omaha Road Bridge Number 15 Omaha Road Bridge Number 15 Omaha Road Bridge Number 15 is a swing bridge that spans the Mississippi River in St. Paul, Minnesota, United States. It was built in 1915 by the Chicago, St. Paul, Minneapolis and Omaha Railway (Omaha Road), though it, and the line from St. Paul to Mendota, was jointly owned with the Chicago, Milwaukee and St. Paul Railway. The bridge was designed by I.F. Stern of Chicago. It is unusually shaped, because the swing span is asymmetrical. According to local legend, the original bridge design had equal length spans on either side of the center pivot.
