Synchronize array with simultaneous access via Photon Network RPC

Hi!

I have list with several items

 var list = new List<int>();
 list.Add(1);
 list.Add(2);
 list.Add(3);
 list.Add(4);

Each player can take item from it, this done locally, not via rpc.
When player take item, rpc sended to other players to remove item from list.

RemoveItemFromList(itemId);
_photonView.RPC("RemoveItem", PhotonTargets.Others, item.Id);

[RPC]
private void RemoveItem(int itemId)
{
   RemoveItemFromList(itemId);
}

private void RemoveItemFromList(int itemId)
{
   var item = list.First(x=>x == itemId);
   list.Remove(item);
}

It’s working normal, but when several players get items simultaneously i have an error. Because two players can hit the same item. How can i sync them?
I am using Photon Cloud.

Solve my problem.
First i check list on master client, and then send changes to all other players.
