Hey everyone I need some help … WebRing counts can be used as descriptors and as ways to classify structures. One way to compute the ring count is to compute the Euler characteristic: #Rings = #Bonds - #Atoms + #Components. Many chemistry toolkits, though not all, implement a ring finding algorithm which identifies the most chemically relevant rings.
