In a certain code, 'CALANDER' is written as 'CLANAEDR'. How is 'CIRCULAR' written in that code?

For question it is clear that, the second and third letters, fourth and fifth letters, sixth and seventh letters of the word mutually interchange positions to form the code.
So
C ⇒ C
I ⇘ R
R ⇗ I
C ⇘ U
U ⇗ C
L ⇘ A
A ⇗ L
R ⇒ R
so the code for CIRCULAR is CRIUCALR
