The chemical compound "(E)-1α,3,4,7,8,9β,10,11-Octahydro-6,10,10-trimethyl-3-<<2-(methylamino)phenyl>sulfinyl>-2H-bicyclo<7.2.0>undecen-2-one" is a complex organic molecule with a unique structure. It is characterized by an octahydro-bicyclo[7.2.0]undecen-2-one core, which features a seven-membered ring fused to a two-membered ring. The molecule contains three methyl groups at positions 6, 10, and 10, and a sulfinyl group attached to a phenyl ring, which itself is substituted with a methylamino group at the 2-position. The "E" configuration indicates the geometric isomerism of the double bond present in the molecule. (E)-1α,3,4,7,8,9β,10,11-Octahydro-6,10,10-trimethyl-3-<<2-(methylamino)phenyl>sulfinyl>-2H-bicyclo<7.2.0>undecen-2-one is known for its potent biological activity and is often associated with natural products and pharmaceuticals, particularly in the context of its potential applications in medicine and chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 81491-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,9 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81491-38:
(7*8)+(6*1)+(5*4)+(4*9)+(3*1)+(2*3)+(1*8)=135
135 % 10 = 5
So 81491-38-5 is a valid CAS Registry Number.
