The LED wiring is off still.
Note that the pins are shown as going across the short length of the body. So you may want to plug the chip in across the middle divider.
I have labelled them A1-7 for the anodes,
and C1-5 for the cathodes.
A1 is pin 9
A2 pin 14
A3 pin 8
A4 pin 4 (also available on pin 12)
A5 pin 1
A6 pin 7
A7 pin 2
C1 pin 13
C2 pin 3
C3 pin 4 (also available on pin 11)
C4 pin 10
C5 pin 6
If you look on the bottom of the part you may see a 1 next to one of the corner pins.
Plug it in and drive the output pin for C1 high (display pin 13) and for R1 low (display pin 9) - should see the corner LED turn on. If not, rotate the display 180 degrees around and try again.
