Is it possible to find the digital sum of first hundred decimal digits of $\sqrt2$?

This question came to my mind when I was finding the digital sum i.e. the repeated sum of $1234^{5678}$ where I had to find $1234^{5678}$ (mod $9$) and then narrow down the remainder to $1$ digit.

sure. Are you looking for an elegant solution? You can do that by brute force by using a computer. You can actually simply use the digits from here. –  Michael Greinecker Jul 22 '12 at 11:07

If this is for Project Euler (for example, problem 80) you should add that as a tag. –  Cocopuffs Jul 22 '12 at 11:11
    
What is project Euler? –  Hyperbola Jul 22 '12 at 11:16

If it's for Project Euler, it's off-limits; they have asked us not to discuss their questions here. –  Gerry Myerson Jul 23 '12 at 0:06
