RotateAround wont rotate to starting position

So what I am trying to do is rotate a game object by 90° to the right. It works great except when rotating from 90° to 0°.

It rotates smoothly everywhere but the last spin in the sequence. If I don't have the check to see if it is moving under RotateRight then I can get it to skip the zero rotation and go back to 270° rotating like it should from 90° to 270°.

Any ideas why it won't rotate the last jump?

 newAngle = 0;
 
 void Update () {
             if (spinRight) {
                 Vector3 spinTo = new Vector3 (0, 0, newAngle);
                 if (Vector3.Distance (board.GetComponent<Transform> ().eulerAngles, spinTo) > 1f) {
                     board.GetComponent<Transform>().RotateAround(board.GetComponent<Transform> ().position, spinTo, -100 * Time.deltaTime);
                 } else {
                     board.GetComponent<Transform> ().eulerAngles = spinTo;
                     spinRight = false;
                 }
             }
     }
     
     public void RotateRight() {
             //if (!spinRight) {
                 newAngle = newAngle - 90;
                 if (newAngle < 0) {
                     newAngle += 360;
                 } else if (newAngle > 360) {
                     newAngle -= 360;
                 }
                 spinRight = true;
             /}
     }
