Reactivity Profile
Ethers, such as 2-ETHOXY-3,4-DIHYDRO-2H-PYRAN can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
Hazard
Moderate fire risk.
Health Hazard
Contact with liquid irritates eyes. Also irritates skin on prolonged contact.
Safety Profile
Moderately toxic by
skin contact. Mildly toxic by ingestion and
inhalation. A skin and eye irritant.
Flammable liquid when exposed to flame,
sparks, and oxidizers. To fight fire, use dry
chemical, foam, fog. When heated to
decomposition it emits acrid smoke and
irritating fumes
Check Digit Verification of cas no
The CAS Registry Mumber 103-75-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103-75:
(5*1)+(4*0)+(3*3)+(2*7)+(1*5)=33
33 % 10 = 3
So 103-75-3 is a valid CAS Registry Number.
