Is the 9450 the most commonly used version of the Delta?

Here's the ULA release:
Cape Canaveral Air Force Station, Fla. (May 23, 2013) -- The launch of a United Launch Alliance Delta IV rocket carrying the Wideband Global SATCOM (WGS-5) satellite for the U.S. Air Force was scrubbed today due to an issue associated with a ground support system helium pressurization line. The launch has been rescheduled for Friday, May 24, at 8:27 p.m. EDT at the opening of a 30-minute window. The forecast for tomorrow shows an 80 percent chance of favorable weather conditions for launch.

The weather was looking bad anyway, even without mechanical problems.

Who calls it a "9450"? ULA doesn't on their web site or in their literature.

Agreed. I don't think the four-digit designations have been used for the Delta IV since it has been in service, and in any case it was revised in the early 2000s by subtracting 5 from the first digit to bring it in line with the numeral in the rocket's name. That never caught on and it was dropped in favour of the M/M+(x,x)/H designations, so:
Delta IV Medium = Delta 4040 = Delta 9040
Delta IV-M+(4,2) = Delta 4240 = Delta 9240
Delta IV-M+(5,2) = Delta 4250 = Delta 9250
Delta IV-M+(5,4) = Delta 4450 = Delta 9450
Delta IV Heavy = Delta 4050H = Delta 9050H*
*I've never understood why this is 9050H not 9250H
The Delta III was the Delta 8930, and in theory it became the 3930, however it only ever flew in one configuration and was pretty much dead by the time they tried to bring the new designations in, so it never stuck.
The Delta II's 7000-series designations continued to be used universally, so the 2000-series designation never caught on. Even ULA uses the 7000-designations.

The 2000, 3000 and 4000 series numbers were from the NLS I contract and not Boeing. They were never used outside of the contract.
