I have an Nvidia GPU GTX 470 - Can I get it's serial number with out opening the case?

**EDIT**
Thanks for all the comments: I tried the Device path as well as the WMIC command (which are the same actually)
Value returned from the WMIC command

```
NVIDIA GeForce GTX 470  PCI\VEN_10DE&DEV_06CD&SUBSYS_079F10DE&REV_A3\4&2F1C4782&0&0018

```

The WMIC (device path is) **2F1C4782** which is translated to: **790382466** (converted to decimal). 

My card SN is: **101500021088** - I think this does not get the correct values.
