Access Iif  to MySQL Case?

I have a simple query that totals weekday vs. weekend sales in MS Access that I need to translate to MySQL.

In Access it is:

SELECT
daily_store_sales.account_code,
Sum(IIf(DatePart("w",[store_report_date]) IN (2,3,4,5,6),qty_daily_sales,0)) AS WDTotal,
Sum(IIf(DatePart("w",[store_report_date]) In (1,7),qty_daily_sales,0)) AS WETotal,
Sum(qty_daily_sales)
FROM
daily_store_sales
GROUP BY
daily_store_sales.account_code

My MySQL translation (of many variations) is not working:

SELECT
daily_store_sales.account_code,
Sum(CASE WHEN DAYOFWEEK([store_report_date]) IN (2,3,4,5,6) THEN SELECT qty_daily_sales ELSE SELECT 0)) AS WDTotal
FROM
daily_store_sales
GROUP BY
daily_store_sales.account_code

Can CASE be used in SELECTs like this?  And if not, what is a better way to handle if/then logic in MySQL queries?

Many Thanks.

yes, but no the SELECT inside the CASE..
Sum(CASE WHEN DAYOFWEEK([store_report_date]) IN (2,3,4,5,6) THEN qty_daily_sales ELSE 0 END)) AS WDTotal
