There's quite a few differences. The terminal of the t and the a are similar, but the perfectly round bowls and O are much more like Futura. Helvetica (basically the font from CAH) also has a slight narrowing on vertical strokes. That g is weird as hell and just looks broken to me. The had to distinguish it from the google font...
That's just plain Helvetica.
It looked like a medley between Futura / Century Gothic and Helvetica to me.
