By studying the extinction curves we can understand the properties of interstellar dust, e.g., the composition and the grain size distribution. The Cardelli, Clayton, & Mathis (1989) law is typically used to fit the extinction data both for diffuse and dense interstellar medium. Here we present the analyses of a large sample of lines of sight with extinction curves covering wavelength range from near infrared (NIR) to ultraviolet (UV). We find that, for some lines of sight, the extinction curves in the UV wavelength region cannot be reproduced well by the Cardelli, Clayton and Mathis formula. We analyze the remaining lines of sight with well-defined RV values in both NIR and UV and conclude that there is a noticeable fraction of the cases with the best fit RV value from NIR data alone different than from UV data alone. We present examples of such extinction curves.
