SQL Server CASE WHEN IN statement

Question

On SQL server 2005 I am trying to query this select statement

SELECT AlarmEventTransactionTableTable.TxnID,
       CASE AlarmEventTransactions.DeviceID
         WHEN DeviceID IN( '7', '10', '62', '58',
                           '60', '46', '48', '50',
                           '137', '139', '142', '143', '164' )
           THEN '01'
         WHEN DeviceID IN( '8', '9', '63', '59',
                           '61', '47', '49', '51',
                           '138', '140', '141', '144', '165' )
           THEN '02'
         ELSE 'NA'
       END AS clocking,
       AlarmEventTransactionTable.DateTimeOfTxn
FROM   multiMAXTxn.dbo.AlarmEventTransactionTable 

It returns the error below

Msg 156, Level 15, State 1, Line 4 Incorrect syntax near the keyword 'IN'.

Please give me some advice on what could be wrong with my code.

Two forms of CASE statements are getting mixed in your query
CASE AlarmEventTransactions.DeviceID should be written just CASE in the query
It should look like:

SELECT
     AlarmEventTransactionTable.TxnID,
     CASE 
    WHEN DeviceID IN('7', '10', '62', '58', '60',
            '46', '48', '50', '137', '139',
             '141', '145', '164') THEN '01'
    WHEN DeviceID IN('8', '9', '63', '59', '61',
            '47', '49', '51', '138', '140',
            '142', '146', '165') THEN '02'
             ELSE 'NA' END AS clocking,
     AlarmEventTransactionTable.DateTimeOfTxn
FROM
     multiMAXTxn.dbo.AlarmEventTransactionTable
