My data is like below:

A B
1 900180111 50000
2 902180111 20000
3 911180111 15000
4 900180121 40000
5 911280121 150000

what i want to do is:

sum of column B which the code in the column A started with 90 or 91 and
ended with 80111 the answer suld be 35000

Based on your criteria, I think the answer should be 85000... the first
three rows of column A start with either 90 or 91 and end with 80111. This
formula produces 85000 as an answer...

=SUMPRODUCT((LEFT(A1:A100,2)={"90","91"})*(RIGHT(A 1:A100,5)="80111")*(B1:B100))
