If you refer to Regex Modification, it later turned out that the specification was far more complicated than stated in the initial question, see below. In order to make this more efficient, can you please confirm the exact requirements. 

1. Number seq. with min 9 and max 15 digits. Like 145-1256-2365-789
2. First 3 and Last 3 should be numbers not diffrentiators. Like 123-1
+545645-123
3. Match can also be without a diffrentiator like 123456789147
4. The diffrentiator(same throughout sequence) can come any number of 
+times between the first and last 3 digits until the min and max lengt
+h criteria is satisfied. Like 1213-456-789-1265
