4-Ethoxy-1,1-diphenyl-penta-1,3-dien, also known as 4-ethoxy-1,1-diphenylbuta-1,3-diene, is an organic compound characterized by a conjugated diene system with a phenyl group attached to each end of the butadiene chain. The molecule features an ethoxy group (an ether functional group) at the 4-position, which is connected to the central carbon atom of the diene. This chemical structure endows the compound with unique reactivity and properties, making it a potential intermediate in the synthesis of various organic compounds, particularly those involving the manipulation of the diene system for the formation of new carbon-carbon bonds. The presence of the ethoxy group also suggests potential applications in the preparation of ethers or as a protecting group in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 4137-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,3 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4137-98:
(6*4)+(5*1)+(4*3)+(3*7)+(2*9)+(1*8)=88
88 % 10 = 8
So 4137-98-8 is a valid CAS Registry Number.
