LT3093 Pin 13 and 1 connected in the chip?

I have soldered an LT3093 to a breakout PCB and I'm trying to determine that Pin 13 (IN, the pad on the bottom) has made a good connection.  I thought I could use a multimeter to see that the resistance between Pin 1 (also IN) and the breakout PCB pad is zero, but when I checked a fresh LT3093 chip by itself, the pad and Pin 1 don't seem to be connected.  Is this true that PIn 13 is not connected to Pins 1 and 2 inside the chip, and that they only become connected by external connections?  Any help on this would be appreciated.
