Xenon difluoride (XeF2) and Arsenic pentafluoride (AsF5) are two distinct chemical compounds. Xenon difluoride is a noble gas compound, where xenon, a noble gas, forms a stable compound with two fluorine atoms. It is a colorless, crystalline solid at room temperature and is highly reactive. Xenon difluoride is used in the production of various xenon compounds and as a fluorinating agent in organic synthesis. Arsenic pentafluoride, on the other hand, is a covalent compound consisting of one arsenic atom and five fluorine atoms. It is a colorless, volatile liquid at room temperature and is highly toxic. AsF5 is used in the production of certain fluorocarbons and as a fluorinating agent in the synthesis of various organic and inorganic compounds. Both compounds are strong fluorinating agents and should be handled with extreme care due to their reactivity and toxicity.

Check Digit Verification of cas no

The CAS Registry Mumber 21308-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,0 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21308-45:
(7*2)+(6*1)+(5*3)+(4*0)+(3*8)+(2*4)+(1*5)=72
72 % 10 = 2
So 21308-45-2 is a valid CAS Registry Number.
