Thanks for the idea:

#include <string.h>
#include <stdio.h>

int main( int argc, char *argv[] ) {
    if ( argc != 2 ) return 1;
    for ( argc = 0; argc < strlen( argv[1] ); ++argc )
        if ( argv[1][argc] < '0' || argv[1][argc] > '9' )
            return 1;
    argc = strlen( argv[1] ) == 1 ? 2 : strlen( argv[1] );
    return ! ( ( argv[1][argc-2] == '0' || argv[1][argc-2] == '5' ) && ( argv[1][argc-1] == 0 || argv[1][argc-1] == '0' ) );
}
