I would like to know if there is some numbers as: 472 A, and other numbers used in the food production are Haram to eat or not.

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

We know nothing concerning what is contained in the product you mentioned in your question. However, if such foods are among what Allah, The Exalted, has made lawful, then it is permissible to eat them, otherwise no.

Nevertheless, if you have doubts about the legality of the content of these products, then you can ask the producing company, and if you cannot verify or it becomes difficult to do so, you have to refrain from eating them.

In this vein, the Prophet said: “Leave that which is doubtful and adopt that which is not doubtful.” [Ahmad, An-Nasaa'i and At-Tirmithi; narrated by Al-Husayn ibn ‘Ali]

Allah knows best.
