    c[1] c[2] c[3] c[4] c[5] c[6] c[7] c[8] dv[1]

    To check whether a RG is correct or not, it has to satisfy the check
    equations:

    c[1]*2 + c[2]*3 + c[3]*4 + c[4]*5 + c[5]*6 + c[6]*7 + c[7]*8 + c[8]*9 +
    dv[9] * 100 = 0 (mod 11)

BUGS
    until now I do not found any RG that has less than 8 digits. But, I
    guess, old people still have it. For now, this is the only way that I
    found to check RG. If you found any bug, feel free to send e-mail, open
    an issue on github or open a RT.

SEE ALSO
    Note that this module only tests correctness. It doesn't enter the merit
    whether the RG number actually exists at the Brazilian government
    databases.

    Please reports bugs via CPAN RT or github.
