Read CSV for variable and check the cells on that line for another variable

I am trying to create a batch file to read a CSV file to find a username that will be a variable then check the next 10 cells on that line if they match another variable which will be a number.

Example CSV:

bsmith, 22, 14, 15, 12, 18, 19
cwright, 10, 15, 11, 2
hwrong, 2, 6, 3
csmith, 10, 16, 19, 3, 5, 19, 18, 7, 2, 4

any help would be greatly appreciated! Thanks

I have this to find the username but now I want to check the numbers if they match another variable:

Variables are: 'username' and 'sitenum'

findstr /c:"%username%" "ACL.csv" >nul 2>&1
IF NOT ERRORLEVEL 1 (
echo AUTHORIZED
) else (
echo UNATHORIZED!!!!
)

I want to check the numbers if they match another variable

Just pipe (|) the output from the first findstr into another findstr as follows:

findstr /c:"%username%" "ACL.csv" | findstr /c:" %sitenum%," >nul 2>&1

Note:

• the leading (space) and trailing , (comma) are important as this prevents 1 matching 11 (for example)

• An A-Z Index of the Windows CMD command line
• A categorized list of Windows CMD commands
• redirection - Redirection operators.
