scriptPubKey with OP

Hello there, I'm trying to make a spliting transcation for Bitcoin's fork BSV. As far I know, there are old satoshis opcodes unlocked.
I've tried to add something like this in output:
OP_DUP OP_HASH160 <somehash> OP_EQUALVERIFY OP_CHECKSIG OP_1 OP_1 OP_MUL OP_DROP
and other combinations, but it always fail without error message. On some tx-broadcast sites it returns just scriptpubkey fail, even with valid stack script with eg. OP_ADD
Is there any restrictions with arithmetic instructions in spending script?

PS. OP_MUL is unblocked in BSV fork
PSS. If this is not a good subforums please move it,

Thanks in advice

Here's some example transaction which I trying to make:
