Chiragh, who was the only Indian to make the cut out of four in the fray, was tied-15th after the second round but was unable to maintain the tempo over the weekend and scored 75-72.
This was his fifth successive cut on the European Tour, but his best finish was only tied-19th at the Thailand Classic.
Meanwhile, China's Ashun Wu claimed his second European Tour title after winning the Lyoness Open by a single shot.
Spain's Adrian Otaegui finished second on 12 under, with Englishman Richard McEvoy another stroke back after dropping his only shot of the day at the 18th.
