Calculate mnemonic code from terminal
Your binary (which includes the 4 checksum bits 0111, or 7) has the leading null's removed.

(0000)1100000 11110001001 00111001011 00100010111 01110111100 11101001010 01011111100 00101001101 01000101111 10001010011 10000110100 00110100111

Which is identical to the binary (without checksum bits 0111) from the web tool:

00001100000 11110001001 00111001011 00100010111 01110111100 11101001010 01011111100 00101001101 01000101111 10001010011 10000110100 0011010....

(Note the missing checksum bits .... at the end)
