Connecting ASM service from Remote Client

Please check my ASM instance based service in two node RAC. 

- Output of lsnrctl services:

 Service "+ASM" has 1 instance(s). 

Instance "+ASM1", status READY, has 1 handler(s) for this service... 

Handler(s): 

"DEDICATED" established:0 refused:0 state:ready 

LOCAL SERVER 

- I added the TNS entry in the client side for ASM instance: 

ASM = 

(DESCRIPTION = 

(ADDRESS_LIST = 

(ADDRESS = (PROTOCOL = TCP)(HOST = server-scan)(PORT = 1521)) 

) 

(CONNECT_DATA = 

(SERVICE_NAME = +ASM) 

) 

) 

But while connecting through client in ASM instance in CDC box, I received 

[oracle@client admin]$ sqlplus sys@ASM as sysasm
