Where can I find this coordinate reference system (wgs84 30N CM 3W) in ArcGIS?

[Elijah]

I have a data with this coordinate reference system (wgs84 30N CM 3W). and I need to load the data in ArcGIS but I can't seem to find it exactly in ArcGIS. First, I will like to know if it's same thing as the usual wgs84 UTM 30N or what is it? Please, how can I deal with this? 

Thanks in advance.
