Uses
2-(Trifluoromethoxy)benzenesulfonyl Isocyanate is an intermediate in the synthesis of 4-Desmethyl Flucarbazone Sodium Salt (D343230), an impurity of Flucarbazone (F148340) and Flucarbazone-sodium (F421125). Flucarbazone is used as a herbicide for agricultural purposes and is an antiparasitic agent.
Check Digit Verification of cas no
The CAS Registry Mumber 99722-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99722-81:
(7*9)+(6*9)+(5*7)+(4*2)+(3*2)+(2*8)+(1*1)=183
183 % 10 = 3
So 99722-81-3 is a valid CAS Registry Number.
