www.example.com/companies/23/brands/39/properties/78

how do i match the properties id(78) with regex from the url

as my try this pattern. 

```
(\/properties\/)([0-9]+)\/?

Match 1
Full match  46-60   `/properties/78`
Group 1.    46-58   `/properties/`
Group 2.    58

```

that match in group2 it's ok. 
but actually i want to match only the digit after `/properties/` only !

How do i design a pattern to match this?

Thank.
