The first character is unrestricted because you have nested keypress handlers. Try this:

$('.Number').keypress(function (event) {

    var keycode = event.which;

    if (!(event.shiftKey == false && (keycode == 46 || keycode == 8 || keycode == 37 || keycode == 39 || (keycode >= 48 && keycode <= 57)))) {

        event.preventDefault();

    }

});
