1,6-Dimethylen-spiro[3.3]heptan is a cyclic organic compound with the molecular formula C9H14. It features a spiro structure, which consists of two rings sharing a common atom, in this case, a carbon atom. The compound has a heptane ring (seven-carbon chain) with a methyl group (CH3) attached to the first and sixth carbon atoms, and a double bond (C=C) between the first and second carbon atoms. This double bond is part of the spiro structure, connecting the heptane ring to a three-carbon ring. 1,6-Dimethylen-spiro[3.3]heptan is an interesting molecule due to its unique structure and potential applications in organic chemistry and pharmaceutical research.
The CAS Registry Mumber 4696-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,9 and 6 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 4696-20: (6*4)+(5*6)+(4*9)+(3*6)+(2*2)+(1*0)=112 112 % 10 = 2 So 4696-20-2 is a valid CAS Registry Number.
