The chemical compound "(3aS)-4t-(3,4-dimethoxy-phenyl)-6,7-dimethoxy-(3ar,9bc)-3a,9b-dihydro-4H-[1,3]dioxolo[4,5-c]chromen-2-one" is a complex organic molecule with a unique structure. It features a chromen-2-one core, which is a type of chromone with an additional oxygen atom in the ring. The compound has a 3aS configuration, indicating the specific arrangement of atoms around the chiral center at position 3a. It also contains a 3,4-dimethoxy-phenyl group, which is a phenyl ring with methoxy groups at the 3 and 4 positions. The molecule has two additional methoxy groups at positions 6 and 7, and a 3a,9b-dihydro structure, which means that there are hydrogen atoms attached to the 3a and 9b positions, reducing the ring's unsaturation. The [1,3]dioxolo[4,5-c] part of the name indicates the presence of a dioxolane ring fused to the chromen core, which contributes to the molecule's overall stability and reactivity. (3aS)-4t-(3,4-dimethoxy-phenyl)-6,7-dimethoxy-(3ar,9bc)-3a,9b-dihydro-4H-[1,3]dioxolo[4,5-c]chromen-2-one is likely to be found in the realm of natural products or as a synthetic intermediate in the pharmaceutical or chemical industry, given its intricate structure and functional groups.

Check Digit Verification of cas no
The CAS Registry Mumber 16821-06-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,2 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.Calculate Digit Verification of CAS Registry Number 16821-06:
(7*1)+(6*6)+(5*8)+(4*2)+(3*1)+(2*0)+(1*6)=100
100 % 10 = 0
So 16821-06-0 is a valid CAS Registry Number.
