Difluoro(fluoroformylimino) sulfur(IV), also known as sulfur tetrafluoride imine, is a chemical compound with the formula SF4N. It is a colorless, unstable, and highly reactive gas that is formed by the reaction of sulfur tetrafluoride (SF4) with nitrogen trifluoride (NF3). Difluoro(fluoroformylimino) sulfur(IV) is an important intermediate in the synthesis of various sulfur-nitrogen compounds and has potential applications in the production of pharmaceuticals and agrochemicals. Due to its high reactivity, it is challenging to handle and requires specialized equipment and techniques for its synthesis and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 3855-41-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,5 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3855-41:
(6*3)+(5*8)+(4*5)+(3*5)+(2*4)+(1*1)=102
102 % 10 = 2
So 3855-41-2 is a valid CAS Registry Number.
