I am trying to learn Irish from a CD program and they have I'm very glad to meet you as "Tá an-áthas orm bualadh leat." and It was nice meeting you. as "Ba dheas casadh leat." My question is why is bualadh ([to] hit) used in the first statement instead of casadh ([to] meet)? Could the first statement be "Tá an-áthas orm casadh leat."?
Thanks

Yes, although some people would object. There is an idiom using "cas" in the autonomous form that has been steadily falling out of use:

Casadh orm é. = I met him. (implies a chance meeting, not a scheduled get-together)

Instead of that, most people now say

Bhuail mé leis. (for both chance encounters and scheduled meetings)

Or they retain the "cas", but use it like "buail":

Chas mé leis.

That's the way it looks to me, anyway. Opinions may differs, esp. since this is a matter of changing usage.

Thank you Dennis

and then as the sonhg has it : "A's cé 'chasfaí damhsa ach gruaigeach chinn óir-bhuí."
