It is a derivative of the xanthene class of compounds, characterized by a spiro-fused structure, which means it has two rings sharing a common carbon atom. The molecule features a phthalan ring (a type of cyclohexanone) and a xanthene ring, with two methyl groups at the 2' and 7' positions, and a carbonyl group at the 3 position. 2',7'-dimethyl-spiro[phthalan-1,9'-xanthen]-3-one is known for its fluorescent properties and is often used as a marker or indicator in various applications due to its ability to emit light when exposed to certain wavelengths. It is also found in some natural products and can be synthesized for research purposes.
The CAS Registry Mumber 125-14-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 5 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 125-14: (5*1)+(4*2)+(3*5)+(2*1)+(1*4)=34 34 % 10 = 4 So 125-14-4 is a valid CAS Registry Number.
