Finding Sentrix ID in HM450K arrays

Hello everyone, I downloaded a methylarray dataset from GEO but unfortunately it doesn't contain Sentrix ID. I checked the .idat file but there is only sentrix position info but not ID. I tried to person who uploads the dataset but the email address in not valid anymore. How can you figure out these kind of problems? Thanks in advance
