Getting a sum of column values

I have a file in the following layout:

201008005946873001846130058030701006131840000000000000000000
201008006784994001154259058033001009527844000000000000000000
201008007323067002418095058034801002418095000000000000000000
201008007697126001722141058029101002214158000000000000000000
201008007947796001042476058034903006788888009999990001234567

I need to add the bolded red column value to get a total.

So result would be 7.

Using C or K shell.

Is there any easy way using awk, SED to do this???
Thanks.

awk '{s+=substr($0,32,2)}END{print s}' file

Awesome, Awesome, Awesome.
Thanks so much.
