Diethylamidosulfurous fluoride, also known as DEASF or compound 33F, is a chemical compound with the formula (C2H5)2NSF3. It is a colorless, volatile liquid that is used as a precursor in the synthesis of various fluorochemicals, including pharmaceuticals and agrochemicals. DEASF is produced by the reaction of diethylamine with sulfur dioxide and fluorine gas. It is a valuable intermediate in the fluorination of organic compounds due to its ability to introduce fluorine atoms into molecules. The compound is also known for its potential use in the production of fluoropolymers and as a reagent in organic synthesis. It is important to handle DEASF with care due to its reactivity and potential health and environmental impacts.

Check Digit Verification of cas no

The CAS Registry Mumber 1550-61-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1550-61:
(6*1)+(5*5)+(4*5)+(3*0)+(2*6)+(1*1)=64
64 % 10 = 4
So 1550-61-4 is a valid CAS Registry Number.
