3,4,5,6-Tetramethyl-cyclohex-4-ene-1,2-dicarboxylic acid anhydride is a complex organic compound with the molecular formula C12H16O3. It is derived from the parent compound cyclohexane, with four methyl groups (CH3) attached to the carbon atoms at positions 3, 4, 5, and 6. The compound features a cyclohexene ring, which is a six-membered carbon ring with a double bond between two of the carbon atoms. The anhydride functional group is formed by the loss of a water molecule (H2O) from two adjacent carboxylic acid groups (COOH), resulting in an ester linkage between the two carboxylic acid groups. This anhydride is a versatile intermediate in organic synthesis, used in the preparation of various pharmaceuticals, polymers, and other specialty chemicals. Its unique structure and reactivity make it a valuable building block in the synthesis of complex molecules.

1448-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1448-73-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 1448-73:
(6*1)+(5*4)+(4*4)+(3*8)+(2*7)+(1*3)=83
83 % 10 = 3
So 1448-73-3 is a valid CAS Registry Number.
