1-Oxaspiro[4.4]nonan-4-one is a cyclic ketone with a unique spiro structure, consisting of a seven-membered ring fused to a four-membered ring. This organic compound is characterized by the presence of a carbonyl group (C=O) and a spiro carbon atom, which connects the two rings. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique structural features and reactivity. The compound is also known for its potential applications in the development of novel materials and as a building block in organic synthesis. Its chemical properties, such as its ability to form enolates and its sensitivity to nucleophilic and electrophilic attacks, make it a valuable tool in the hands of chemists for constructing complex molecular architectures.

68978-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68978-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,9,7 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68978-78:
(7*6)+(6*8)+(5*9)+(4*7)+(3*8)+(2*7)+(1*8)=209
209 % 10 = 9
So 68978-78-9 is a valid CAS Registry Number.
