Task: Please create a SMILES based on the text description below.
Description: The molecule is an oxopurine that is xanthine in which the hydrogen attached to the nitrogen at position 7 is replaced by a methyl group. It is an intermediate metabolite in the synthesis of caffeine. It has a role as a plant metabolite, a human xenobiotic metabolite and a mouse metabolite. It is an oxopurine and a purine alkaloid. It derives from a 7H-xanthine.
Result: Cn1cnc2[nH]c(=O)[nH]c(=O)c21
