ArrayFormula to extract part of the string

Question

I have come across the below formula, and I am finding it quite useful, I want to turn it into an array shortly, but before I do, I was wondering if there was an easier way to do this?

=if(len(LEFT(MID(A2,SEARCH("02",A2)+2,LEN(A2)),SEARCH("37",MID(A2,SEARCH("02",A2)+2,
 LEN(A2)))-1))=14,LEFT(MID(A2,SEARCH("02",A2)+2,LEN(A2)),SEARCH("37",MID(A2,SEARCH("02",A2)+2,
 LEN(A2)))-1),if(len(LEFT(MID(A2,SEARCH("02",A2)+2,LEN(A2)),SEARCH("15",MID(A2,SEARCH("02",A2)+2,
 LEN(A2)))-1))=14,LEFT(MID(A2,SEARCH("02",A2)+2,LEN(A2)),SEARCH("15",MID(A2,SEARCH("02",A2)+2,
 LEN(A2)))-1),if(len(LEFT(MID(A2,SEARCH("02",A2)+2,LEN(A2)),SEARCH("10",MID(A2,SEARCH("02",A2)+2,
 LEN(A2)))-1))=14,LEFT(MID(A2,SEARCH("02",A2)+2,LEN(A2)),SEARCH("10",MID(A2,SEARCH("02",A2)+2,
 LEN(A2)))-1),"")))
