Below I have listed seven numbers, but I have coded them by consistently replacing digits with letters, with different letters used for different digits: CINEMA, ECZEMA, EMMA, ENEMA, ENIGMA, MAMMA, STIGMA. All but one of the seven numbers is divisible by 9.

Which word represents the number which is not divisible by 9?

WIN £15 will be awarded to the sender of the first correct answer opened on Wednesday 29 June. The Editor’s decision is final. Please send entries to Enigma 1648, Âé¶¹´«Ã½, Lacon House, 84 Theobald’s Road, London WC1X 8NS, or to enigma@newscientist.com (please include your postal address).

The answer to Enigma 1642, and the winner, will appear next week.
