I took the index with the words, transformed the range to binary, extra 3 zeros, calculated the sha256 digest, took the main part of the hexadecimal to transform it to binary, extra 3 zeros to your eight digits on the binary and obtained 00000010011 which translates to 19 in decimal. https://www.animenewsnetwork.com/bbs/phpBB2/profile.php?mode=viewprofile&u=1025088
