Check multiple columns to see if they start with certain number patterns

Hi,

I have 6 cells in an excel worksheet that I am interested in. I need to check if these 6 cells START with 531, 532, 533 OR 534. If it does start with one of these numbers, input a 1, otherwise input a 0.
For example, a cell with the value of:
534929 would give me a 1
953429 would give me a 0
3945 would give me a 0
532 would give me a 1

So far, I have been able to check one cell if it starts with one pattern of numbers (531 in this case) using this formula:

=If(ISNUMBER(SEARCH(531,(LEFT(CELLNUMBER,3)))),1,0)

However, I am unsure how to incorporate more columns/number patterns into this formula.

Can anyone help me with this?

Thanks.

My apologies, I forgot to mention that the patterns could potentially include letters, so boop and TMS' solutions don't work.

XOR LX I think your solution works, but I am wondering how I could make it so it checks multiple cells?

Sorry if there is a simple solution, I am just not sure how to make the necessary brackets work.

Thanks again.

So let's say there are six columns. I want to check all six columns at the same time to see if any column cell starts with 531,532,533,534.

Only then do I want to drag the formula down to give equivalent results for strings in A2, A3, etc.

Thanks

Alright, that seems to work! When I entered it in as a regular formula it kept giving me an error.

Thanks a lot, you've been a lot of help.
