user88340: I'm trying to spend coins from this tx

The scriptpubkey is simple:
1 OP_CHECKSEQUENCEVERIFY OP_DROP OP_SHA256 6b86b273ff34fce19d6b804eff5a3f5747ada4eaa22f1d49c01e52ddb7875b4b OP_EQUAL

SHA256 (1) = 6b86b273ff34fce19d6b804eff5a3f5747ada4eaa22f1d49c01e52ddb7875b4b 
So, I just need to push 1 to the stack using OP_1
Here is my transaction:

      }
    }
  ]
}

When I use sendrawtransaction I got 
mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack element) (code 16)

Is my redeem script wrong? Or it's something wrong with the scriptpubkey ?

user60443: The SHA256 of 1 is 4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a
$ printf "01" | xxd -r -p | openssl sha256

You were probably trying to do the SHA256 of the ascii character "1" which has a byte value of 0x31 or 41 in decimal.
