Can I join the music box? The magic music box (MMB)

This explains the motivation for the challenge, feel free to ignore.

The magic music box is a word game played by a group of people, where one is the owner of the magic music box and the other people are trying to put words inside the magic music box.

Rules for the game with humans: the game goes in turns, one person at a time. In your turn, you have to say a word you want to put in the MMB and the MMB owner says if your word can get in or not, depending on the game criterion. If you are the MMB owner, you have to say a word that can go in the MMB.

The task

You have to code a function/program that receives a word as input (in any sensible format) and outputs Truthy or Falsy. Truthy if the word can go in the MMB and Falsy otherwise.

For a word to be able to go in the MMB, it has to contain at least one of the following seven strings:


do
re
mi
fa
sol
la
si


Input

A lowercase "word" in any sensible format, for example:


a string
a list of characters
a list of ASCII values of the characters
