1,4-Cyclohexadiene, 1,3-dimethyl- is an organic compound with the molecular formula C8H12. It is a cyclic hydrocarbon with a six-membered ring structure, where two carbon atoms (C1 and C4) are double-bonded, and two methyl groups (CH3) are attached to the adjacent carbon atoms (C1 and C3). 1,4-Cyclohexadiene, 1,3-dimethyl- is a colorless liquid with a pungent odor and is insoluble in water. It is used as a chemical intermediate in the synthesis of various organic compounds, such as polymers and pharmaceuticals. Due to its reactive nature, it is sensitive to light, heat, and air, and should be stored under controlled conditions to prevent decomposition.

4074-20-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4074-20-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4074-20:
(6*4)+(5*0)+(4*7)+(3*4)+(2*2)+(1*0)=68
68 % 10 = 8
So 4074-20-8 is a valid CAS Registry Number.

REVERSAL OF THE REGIOSELECTIVITY OF THE BIRCH REDUCTION OF XYLENES

Epling, Gary A.,Florio, Emily

, p. 1469 - 1472 (2007/10/02)

The "Photo-Birch" reduction of o-, m-, and p-xylene, using NaBH4, 1,3-dicyanobenzene, and photolysis, gives 1,4-dienes as products.The regioselectivity of these reactions is greatly different from the normal Birch reduction.
