How to create an array and loop in DAX

I have a large amount of data with a lot of different work centers, but I want to calculate workcenter1(good parts/total parts) * workcenter2(good parts/total parts) * ... but only for a certain list of workcenter numbers. Is there a way to create the list of work centers in DAX or do I need to create a new column with M to create that list?

This is a mishmash of the code that is working and what I would like to do with it:

array BR41 = {"670205","670206","670302","670502","670902","670904","671002","671202"};
float RolledYield = 1;

for(int i=0;i<=7;i++)
{
string LoopedWorkcenterNumber = BR41[i];
float RolledYield = RolledYield *

// DAX code I have been using for calculating the filtered yield data
DIVIDE( CALCULATE( SUM(DWS_ConfPassAndScrap[PassQuantity]),FILTER(ALL(DWS_ConfPassAndScrap[Workcenternumber]),DWS_ConfPassAndScrap[Workcenter]= LoopedWorkcenterNumber)),
CALCULATE(SUM(DWS_ConfPassAndScrap[PassQuantity]),FILTER(ALL(DWS_ConfPassAndScrap[Workcenter]),DWS_ConfPassAndScrap[Workcenter]=LoopedWorkcenterNumber))
+CALCULATE(SUM(DWS_ConfPassAndScrap[ScrapQuantity]),FILTER(ALL(DWS_ConfPassAndScrap[Workcenter]),DWS_ConfPassAndScrap[Workcenter]=LoopedWorkcenterNumber)))

}
