Task: Please create a SMILES based on the description below.
Description: The molecule is an azamacrocyle in which four nitrogen atoms at positions 1, 4, 7 and 10 of a twelve-membered ring are each substituted with a carboxymethyl group. It has a role as a chelator. It derives from a hydride of a 1,4,7,10-tetraazacyclododecane.
Result: O=C(O)CN1CCN(CC(=O)O)CCN(CC(=O)O)CCN(CC(=O)O)CC1
