Bicyclo[2.2.1]heptane, 2-ethylidene-, also known as norcarane, is a bicyclic hydrocarbon with the molecular formula C9H14. It features a seven-membered ring with two carbon atoms forming a bridge to create a second ring. The 2-ethylidene group is a vinyl substituent attached to the second carbon atom of the seven-membered ring. Bicyclo[2.2.1]heptane, 2-ethylidene- is an important building block in organic synthesis, particularly for the preparation of various norbornane derivatives, which have applications in pharmaceuticals, agrochemicals, and materials science. Norcarane is known for its unique strain and rigidity due to the presence of the bridgehead double bond, which influences its reactivity and physical properties.

2146-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2146-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2146-40:
(6*2)+(5*1)+(4*4)+(3*6)+(2*4)+(1*0)=59
59 % 10 = 9
So 2146-40-9 is a valid CAS Registry Number.

ORGANIC PHOTOCHEMISTRY WITH 6.7eV PHOTONS: DECOMPOSITION OF 1,1-DISUBSTITUTED CYCLOPROPANES IN SOLUTION

Srinivasan, R,Baum, Thomas,Ors, Jose A.

, p. 4795 - 4798 (1981)

The course of the two-bond cleavage reactions of cyclopropanes in photolysis at 185nm in solution is strikingly influenced by disubstitution of one of the carbons in the ring.
