"6-{[(methylsulfonyl)oxy]methyl}-4-oxo-4H-pyran-3-yl methanesulfonate" is a complex organic chemical compound with the molecular formula C8H10O8S2. It is characterized by a pyran ring structure, which is a six-membered cyclic structure containing one oxygen atom. The compound features a methylsulfonyl group attached to a methylene bridge, which in turn is connected to the pyran ring. The pyran ring itself carries a 4-oxo group, indicating the presence of a carbonyl group at the 4-position. Additionally, it has a methanesulfonate group, which is a methane molecule with a sulfonic acid group attached. 6-{[(methylsulfonyl)oxy]methyl}-4-oxo-4H-pyran-3-yl methanesulfonate is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, particularly as an intermediate in the production of certain drugs. Its chemical structure and properties make it a versatile building block in organic synthesis, although it is important to handle such compounds with care due to their potential reactivity and toxicity.

5443-45-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5443-45-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,4 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5443-45:
(6*5)+(5*4)+(4*4)+(3*3)+(2*4)+(1*5)=88
88 % 10 = 8
So 5443-45-8 is a valid CAS Registry Number.
