In Kazakhstan all tourist visas must be registered with the immigration police. This is usually done automatically upon entry to the country especially if arriving at an airport.
If your tourist visa card has two stamps then it is registered. If it only has one stamp then you must go to the Office of Visas and Registration (OVIR) office and register within five days of arrival. The entry date counts as one day.
