938-22-7 Usage
General Description
2,3,4,6-Tetrachloroanisole, also known as 2,4,6-Trichloroanisole or TCA, is a chemical compound that is often associated with cork taint in wine. It is formed when natural compounds in cork come into contact with chlorine-containing compounds, such as those used in disinfectants or pesticides. 2,3,4,6-Tetrachloroanisole has a musty, moldy odor and can impart a similar off-flavor to affected wines. It is highly volatile and can easily contaminate entire batches of wine, resulting in significant economic loss for wineries. Efforts are made to prevent and minimize the presence of 2,3,4,6-Tetrachloroanisole in wine through careful handling and storage of cork products.

The CAS Registry Mumber 938-22-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 938-22:
(5*9)+(4*3)+(3*8)+(2*2)+(1*2)=87
87 % 10 = 7
So 938-22-7 is a valid CAS Registry Number.
