I'm an employer in California. Is the SDI I pay on my employee's wages deductible on my Federal taxes?

I run a sole proprietorship with 3 employees.  I pay SDI (State Disability Insurance) on their wages to the State Of California.  This is basically a tax that the state mandates.  It's about 1% of the total wages I pay to my employees.  

Is this SDI I pay deductible on Schedule C?
