Meso-butane-1,2,3,4-tetracarboxylic acid tetramethyl ester is a complex organic compound with the chemical formula C12H16O8. It is a derivative of butane-1,2,3,4-tetracarboxylic acid, where all four carboxylic acid groups are esterified with methanol, resulting in the formation of four methyl ester groups. meso-butane-1,2,3,4-tetracarboxylic acid tetramethyl ester is characterized by its symmetrical structure, with two pairs of adjacent carboxylic acid groups on a butane chain. It is often used in the synthesis of various organic compounds and as a building block in the preparation of complex molecules, such as pharmaceuticals and polymers. The meso-isomer specifically refers to the optical isomer that has a plane of symmetry, making it distinct from other possible isomers of butane-1,2,3,4-tetracarboxylic acid tetramethyl ester.

1641-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1641-42-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1641-42:
(6*1)+(5*6)+(4*4)+(3*1)+(2*4)+(1*2)=65
65 % 10 = 5
So 1641-42-5 is a valid CAS Registry Number.
