812-04-4 Usage
Reactivity Profile
1,1-dichloro-1,2,2-trifluoro-ethane is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. They suffer oxidation with strong oxidizing agents and under extremes of temperature.
Check Digit Verification of cas no
The CAS Registry Mumber 812-04-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 812-04:
(5*8)+(4*1)+(3*2)+(2*0)+(1*4)=54
54 % 10 = 4
So 812-04-4 is a valid CAS Registry Number.
