General Description
Propanoic acid, 3-[(2,3-dihydrothieno[3,4-b]-1,4-dioxin-2-yl)methoxy]- is a chemical compound that contains propanoic acid and a 3-[(2,3-dihydrothieno[3,4-b]-1,4-dioxin-2-yl)methoxy] group. Propanoic acid is a carboxylic acid with the formula CH3CH2COOH, commonly used as a preservative in the food and pharmaceutical industries. The 3-[(2,3-dihydrothieno[3,4-b]-1,4-dioxin-2-yl)methoxy] group indicates the presence of a thieno-dioxin ring structure attached to a methoxy group. Propanoic acid, 3-[(2,3-dihydrothieno[3,4-b]-1,4-dioxin-2-yl)methoxy]- may have potential applications in pharmaceutical research or industrial processes requiring the properties of propanoic acid combined with those of the thieno-dioxin ring structure. Further research and testing would be needed to fully understand its properties and potential uses.
Check Digit Verification of cas no
The CAS Registry Mumber 853799-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,7,9 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 853799-71:
(8*8)+(7*5)+(6*3)+(5*7)+(4*9)+(3*9)+(2*7)+(1*1)=230
230 % 10 = 0
So 853799-71-0 is a valid CAS Registry Number.
