How to read Layer in AutoLisp

How to read layer from poline?

e.g with this i can get (8. "LAYER_NAME") but i wanna see onyl LAYER_NAME because I want to later check by name something

(defun c:test ( / ent enx )
    (if (setq ent (car (entsel)))
        (progn
            (setq enx (entget ent))
            (assoc 8 enx)
        )
    )
)

>Solution :

Change the line

(assoc 8 enx)

to

(cdr (assoc 8 enx))
