There is no provision for sick leave under Factories Act and so far as the Shops and Establishmenst Act is concerned it depends up on the Shops Act of your State. Check with your State Act. So far as my knowledge stetches, Shops Acts of the States provide for encashment of annual leave/earned leave/privilege laeave but not sick leave.Thus it leaves the question to company's policy. If your company's plocy does not provide for encashment of sick leave, you cannot claim it.
