how to say---"is that right"?
Actually, ¿no es así? (isn't that the way it is?) can be correct, too. It just depends on what you mean by "right." Although, I think ¿es así? would be closer.
¿Es verdad? (Is that true?)
¿Es correcto? (Is that correct?)
¿De veras? (Is that true? / Really?)
¿En serio? (Seriously? / Really?)
¿Es así? (Is it like that? / Is that the way it is?)
¿Es justo? (Is that fair?)
¿Es real? (Is that real?)
I can think of a couple of contexts for this question where the answer would be different.
I hear the preacher on Sunday ask "is that so?" (rhetoric) by a simple "¿si o no?"
If you are asking for a specific confirmation of information, I would use
¿es este correcto?
literally, is that correct.
I'm sure others will have better solutions. There may be other contexts, too.
Hope that helps!
