General Description
7-NORBORNADIENYLBENZENE is a chemical compound that consists of a norbornadienyl group attached to a benzene ring. It is a colorless liquid with a pungent odor and is commonly used as a precursor in organic synthesis. It is also used as a crosslinking agent in the production of polymers and resins. Additionally, it can be utilized as a building block in the synthesis of various pharmaceutical and agrochemical compounds. Due to its highly reactive nature, 7-NORBORNADIENYLBENZENE requires proper handling and storage to prevent accidental exposure and potential adverse health effects.
Check Digit Verification of cas no
The CAS Registry Mumber 40156-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,5 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40156-12:
(7*4)+(6*0)+(5*1)+(4*5)+(3*6)+(2*1)+(1*2)=75
75 % 10 = 5
So 40156-12-5 is a valid CAS Registry Number.

Synthesis and Use of 7-Substituted Norbornadienes for the Preparation of Prostaglandins and Prostanoids
Baxter, Anthony D.,Binns, Falmai,Javed, Tariq,Roberts, Stanley M.,Sadler, Peter,et al.
, p. 889 - 900 (2007/10/02)
Syntheses of 7-substituted norbornadienes from 7-t-butoxy- and 7-halogeno-norbornadienes are described.Rearrangement of the products in the presence of peracetic acid gives bicyclic aldehydes (2) in equilibrium with enol ethers (3) which are hydrolysed to hydroxycyclopentenylacetaldehydes (4), and converted into key intermediates for the synthesis of prostaglandins and their analogues.Syntheses of prostaglandin J analogues with n-hexyl and phenyl groups replacing the ο-side-chain are described.
