There are two ways to find out :-
1. Yellow line : In case of CBC coaches, yellow line is painted at the ends of the coaches.
2. Absence of buffers : Buffers are anti-collision devices that are present at the ends of each coaches. In CBC, the coupler itself acts like a buffer.

Few coaches do have buffers.

---

Those are SLR/EOG coaches i.e. coaches at the ends.

---

I have seen SL coaches with buffers too. In fact when I travelled by SSPN SF, my coach had buffers and SLR didnt have buffer. :) Some SLRs dont have buffers.

---

Maybe those coaches initially had screw coupling and later on retrofitted with CBC.
