May be low quality or a scam, not connected to any university, trying to get fees from you "immediately".
As far as I can tell this organisation has no real affiliation to any university, and is a low quality organisation or maybe a scam to get registration fees from young researchers by telling them their "abstract has been accepted for an oral presentation". Their organiser used a gmail address and pressured a colleague to pay a high registration fee. Links to "advisory board" and "organisational board" members and profiles don't work, and I couldn't find any university contact details for the chair, who was a business person not an academic.
The programme has real titles, but on a very broad range of topics, no clear focus i could detect. If you want to hear a particular presentation I strongly recommend contacting the speaker listed at their university contact and asking if they are really attending, and if they know anyone else who is, and why they chose this conference - was it by any chance an email invitation after their email was visible on a recent publication?
If you think of going to one of their conferences, I suggest contacting the advisory board members at their university email and phone, and ask if they are attending and presenting, or calling the hotel where the conference is supposed to happen and see if CRG has really booked a conference there on the dates they claim.
