1901-34-4 Usage
General Description
2,4-Cycloheptadien-1-one is a chemical compound known for its strong aroma and yellow color. It is used in the production of fragrances, as well as in organic synthesis and chemical research. The compound is highly reactive due to the presence of an alpha, beta-unsaturated ketone group, and is susceptible to nucleophilic addition reactions. It is also a key intermediate in the synthesis of various pharmaceuticals and other organic molecules. The compound is sensitive to light and air, and should be stored in a cool, dark place to prevent degradation.
Check Digit Verification of cas no
The CAS Registry Mumber 1901-34-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1901-34:
(6*1)+(5*9)+(4*0)+(3*1)+(2*3)+(1*4)=64
64 % 10 = 4
So 1901-34-4 is a valid CAS Registry Number.

[reaction: see text] The efficient construction of an ingenol intermediate exhibiting insideminus signoutside intrabridgehead stereochemistry is reported. The sequence features the net conversion of a cis-intrabridgehead compound into a highly strained trans-species via palladium-mediated isomerization of an allylic epoxide followed by a low-temperature alkoxide-accelerated 1,5-hydrogen migration.
