Abstract : The study of interstellar matter is important for many investigations related to galactic and extragalactic objects. The attenuation of star light due to interstellar matter is known as interstellar extinction. Interstellar extinction law is the best tool to study the interstellar matter. In the present study we have investigated the interstellar extinction law in the direction of five young open star clusters namely NGC 6823, NGC 7160, NGC 2401, Haffner 18 and Haffner 19. The optical and near-IR data for these clusters have been taken from WEBDA and 2MASS database respectively. All these objects are younger than 50 Myr. The derived colour excess ratios indicate that interstellar extinction law is normal in the direction of these clusters. This also indicates that the properties of interstellar matter is normal.
