Middle English (originally as used in the game of chess): the noun and exclamation from Old French eschec, from medieval Latin scaccus, via Arabic from Persian šāh 'king'; the verb from Old French eschequier 'play chess, put in check'. The sense 'stop, restrain, or control' arose from the use in chess, and led (in the late 17th century) to 'examine the accuracy of, verify'
