One of the advantages of web services is development of the software through composition of web services, which use existing web services as a component to create software on demand, for composition to be useful and valid in development of the software, web services composition need to be validated for correctness. In this paper, we have formally represented web services using Pi-Calculus. It is a kind of process algebra which can be used to model dynamic concurrent systems and behavior of web services composition is very close to it. For verification the tool MWB (Mobility Workbench) has been used.
