You could use the following regular expression:
```
/^\S*[A-Z]\S*[A-Z]\S*$/
```
[**Example Here**](https://regex101.com/r/mM2dQ1/1)
* `^` - Anchor denoting the start of the line

([a-z0-9]*[A-Z][a-z0-9]*[A-Z]\w*)
```
This seems to work based on <http://regexr.com/>
Basically I use \*, which means optional with any ammount, so it could have from 0 to whatever number regex support of characters from a-z or 0-9, then I expect at least 1 upper case, followed again by 0 to infinite characters... |
