(1S,4R,6S)-5,5,10,10-Tetrachloro-tricyclo[7.1.0.0^4,6]decane, also known as α-HCH or α-hexachlorocyclohexane, is a chemical compound with the molecular formula C10H8Cl4. It is one of the eight isomers of hexachlorocyclohexane, a group of chemicals widely used as pesticides. α-HCH is a white crystalline solid with a low melting point and is known for its insecticidal properties. It was once extensively used in agriculture and public health, but due to its persistence in the environment and potential health risks, its use has been restricted or banned in many countries. The compound is characterized by its chiral center, which gives it a specific spatial arrangement of atoms, and it is one of the more stable and less toxic isomers compared to others like γ-HCH, which is more hazardous.

Check Digit Verification of cas no

The CAS Registry Mumber 62990-22-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,9,9 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 62990-22:
(7*6)+(6*2)+(5*9)+(4*9)+(3*0)+(2*2)+(1*2)=141
141 % 10 = 1
So 62990-22-1 is a valid CAS Registry Number.

Different synthetic pathways are discussed for the title compounds 15 and 45, which can be trapped in solution.Their average lifetimes are to low for an isolation in pure state.Isomerisations on the C8H8-energy hypersurface lead to styrene (47) and/or benzocyclobutene (22).
