4(2H)-Benzofuranone, 2-ethoxy-3,5,6,7-tetrahydro-3,6-dimethyl-, (2R,3S)-rel-(9CI) is a complex organic compound with the molecular formula C12H16O3. It belongs to the class of benzofuranones, which are derivatives of benzofuran, a heterocyclic aromatic compound containing an oxygen atom. This specific compound features a 2-ethoxy group, which is an ethyl ether functional group attached to the benzofuranone core. Additionally, it has a 3,5,6,7-tetrahydro structure, indicating the presence of four hydrogen atoms bonded to the carbon atoms, and 3,6-dimethyl substituents, which are two methyl groups attached to the carbon atoms at positions 3 and 6. The (2R,3S)-rel stereochemistry describes the spatial arrangement of these substituents around the molecule. 4(2H)-Benzofuranone,2-ethoxy-3,5,6,7-tetrahydro-3,6-dimethyl-,(2R,3S)-rel-(9CI) is primarily of interest in the field of organic chemistry and may have potential applications in the synthesis of pharmaceuticals or other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 643760-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,6 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 643760-08:
(8*6)+(7*4)+(6*3)+(5*7)+(4*6)+(3*0)+(2*0)+(1*8)=161
161 % 10 = 1
So 643760-08-1 is a valid CAS Registry Number.
