String variables functions

Hello everyone, I have a dataset with a string variable like this:

name

Duomo (1)
Brera (2)
Giardini Porta Venezia (3)
Guastalla (4)
Vigentina (5)
Ticinese (6)
Magenta - S. Vittore (7)

I want to create two new variables: in the first one I want to have only the name and in the second one the value between parenthesis.

Which command I have to use? Someone could help me?
Thank you in advance.
