It's an S-125 variant. Undeveloped prototype.

 From the book of Mikhail Pervov "Anti-aircraft missile weapons of the country's air defense":

The missile under the index 625 for the 125th complex was developed in the design bureau under the leadership of M.G. Ollo. In the design of the rocket, a solid propellant sustainer engine was used for the first time. Station tests and autonomous missile launches were carried out in Kapyar. Difficulties arose at the stage of complex testing. When launching missiles, it was not possible to get into a given sector of the radar - each time the rocket left the given point for a considerable distance. Conducted ten unsuccessful launches. For a long time they searched for the cause, but did not find it. The situation was getting critical."

The experimental sample included a missile guidance station with an antenna post, two-rocket launchers and a 625 solid-propellant rocket. Tests of the guidance station went well. However, missile tests have stalled.

At the very first launches of the 625th rocket, we encountered an incomprehensible phenomenon: the rocket constantly left the sector of responsibility to the left. We tried many options to keep it in the sector: we put mechanical programmers into the system of control commands, carried out all kinds of manipulations with the angles of shooting into the sector ... Nothing helped! Not a single firing in a closed control loop could be carried out. The missile was returned to the factory for revision."

      In 1959, Ollo brought several modified rockets to the test site. As it turned out, the reason for the unsuccessful launches was simple. On the drawing of the docking cone of the first and second stages, the vertical dimension of the cone was indicated on one side as 558 mm, and on the other side as 553 mm, although both dimensions should be the same. Someone, by mistake, wrote a three instead of an eight, as a result, the cone turned out to be "curved" during manufacture, and the rocket - "curved". The difference of five millimeters was not noticeable to the eye, but invariably manifested itself in flight. This insignificant oversight led to the failure of the tests. The work of a large team of designers, workers, testers and huge material resources were spent in vain.''

The S-125 is called Neva, aka SA-3 Goa in NATO parlance. As for V-625 specifically, it appears only a few test units were produced before the project was aborted  due to the aforementioned manufacturing flaws. SA-3s are in use today, afaik, so further development certainly took place.
