Description
Selenium oxide (SeO3)(6CI,7CI,8CI,9CI) is a white solid that exists in the form of white crystals. It is hygroscopic, meaning it has the ability to absorb moisture from the air. Selenium oxide (SeO3)(6CI,7CI,8CI,9CI) can be synthesized by reacting sulfur trioxide (SO3) with potassium selenate or by reacting phosphorus pentoxide with selenic acid. Selenium oxide is a strong oxidizing agent and remains stable in dry air at room temperature. However, it decomposes upon heating, first forming selenium pentoxide and then selenium dioxide.
Uses

Air & Water Reactions
Reacts vigorously with water to form selenic acid solution.
Reactivity Profile
Inorganic oxidizing agents, such as Selenium trioxide, can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Explosive mixtures of inorganic oxidizing agents with reducing agents often persist unchanged for long periods if initiation is prevented. Such systems are typically mixtures of solids, but may involve any combination of physical states. Some inorganic oxidizing agents are salts of metals that are soluble in water; dissolution dilutes but does not nullify the oxidizing power of such materials. Organic compounds in general have some reducing power and can in principle react with compounds in this class. Actual reactivity varies greatly with the identity of the organic compound. Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates.
Health Hazard
Absorption of selenium may be demonstrated by presence of the element in the urine and by a garlic-like odor of breath. Inhalation can cause bronchial spasms, symptoms of asphyxiation, and pneumonitis. Acute symptoms of ingestion include sternal pain, cough, nausea, pallor, coated tongue, gastrointestinal disorders, nervousness and conjunctivitis. Contact with eyes or skin causes irritation.
Check Digit Verification of cas no
The CAS Registry Mumber 13768-86-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,6 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13768-86:
(7*1)+(6*3)+(5*7)+(4*6)+(3*8)+(2*8)+(1*6)=130
130 % 10 = 0
So 13768-86-0 is a valid CAS Registry Number.
