"2H-Pyran-5-carboxylic acid, 4-methoxy-6-methyl-2-oxo-, ethyl ester" is a complex organic compound with the chemical formula C12H14O5. It is a derivative of 2H-pyran-5-carboxylic acid, characterized by the presence of a 4-methoxy-6-methyl-2-oxo group. This molecule features a pyran ring, which is a six-membered oxygen-containing cyclic structure, with a carboxylic acid group at the 5-position. The 4-methoxy group introduces a methoxy substituent at the 4-position, while the 6-methyl group adds a methyl substituent at the 6-position. The 2-oxo indicates the presence of a carbonyl group at the 2-position, which, along with the carboxylic acid group, contributes to the molecule's reactivity. The ethyl ester functional group is attached to the carboxylic acid, forming an ester linkage and providing the compound with its specific chemical properties. 2H-Pyran-5-carboxylic acid, 4-methoxy-6-methyl-2-oxo-, ethyl ester is synthesized through a series of chemical reactions and is used in various applications, such as in the pharmaceutical industry and as a synthetic intermediate in the preparation of other organic compounds.

668-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 668-41-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.Calculate Digit Verification of CAS Registry Number 668-41:
(5*6)+(4*6)+(3*8)+(2*4)+(1*1)=87
87 % 10 = 7
So 668-41-7 is a valid CAS Registry Number.
