Around the world, Kasto (Kasto 
, Schachtel 
) is quite a rare primarily male, but scarcely feminine forename. The forename Kasto is characteristic of Tanzania, where it is quite a rare boy's name, Indonesia, and Saudi Arabia, where it is a very rare boy's name. Not in comparison with a country's population, the name is most common in Indonesia, Tanzania, and India. Very seldom, Kasto is the last name as well as the forename.
