The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').

Deuterium, D, 2 D (= hydrogen-2, 2 H). Tritium, T, 3 T (= hydrogen-3, 3 H). Chemical formulae with deuterated solvents (for example, in NMR use) are customarily described with "D" as chemical symbol: CD 3 OD, methanol-d 4; CD 3 SOCD 3, DMSO-d 6 (regular notation would be C 2 H 3 O 2 H). These established systems are acceptable, provided they ...
The prefix form is "carbamoyl-". e.g., HCONH 2 methanamide, CH 3 CONH 2 ethanamide. Amides that have additional substituents on the nitrogen are treated similarly to the case of amines: they are ordered alphabetically with the location prefix N: HCON(CH 3) 2 is N,N-dimethylmethanamide, CH 3 CON(CH 3) 2 is N,N-dimethylethanamide.
