16949-65-8 Usage
General Description
Crystalline solid. Decomposes at 120°C. Contact may cause slight irritation to skin, eyes, and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals.
Air & Water Reactions
Water soluble.
Reactivity Profile
Magnesium fluosilicate gives basic aqueous solutions. Reacts with acids. Does not usually react as either oxidizing agents or reducing agents.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
Flammability and Explosibility
Nonflammable
Safety Profile
Moderately toxic by
ingestion. When heated to decomposition it
emits toxic vapors of magnesium and F-.
Check Digit Verification of cas no
The CAS Registry Mumber 16949-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,4 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16949-65:
(7*1)+(6*6)+(5*9)+(4*4)+(3*9)+(2*6)+(1*5)=148
148 % 10 = 8
So 16949-65-8 is a valid CAS Registry Number.
