You're better off creating an array of ids. When it you roll, you can then see if that id is in your array, and then move forward.

var possiblePositions = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24]

function randomSpin(sides) {
 return Math.floor(Math.random() * (sides || 6) ) + 1;
}
var $currentPiece = $('piece.active');
var currentSpot = $currentPiece.attr('spotPosition');
var spin = randomSpin(6) + randomSpin(6);
var nextSpot = currentSpot + spin;

if (possiblePositions.indexOf(nextSpot)) {
    $('#div' + nextSpot).append($currentPiece);
}
