Serious eye damage/eye irritation - Category 2A-2B
Specific target organ toxicity - Single exposure - Category 1 (respiratory system, heart, blood system, liver)
Specific target organ toxicity - Repeated exposure - Category 1 (respiratory system),
Category 2 (nervous system)
Flammable - 4th degree, Reactive - 3rd degree
Hazards Summary:
Experimental animals show signs of respiratory irritation and die after 8 hour exposures of 1 mg/m3 (0.3 ppm). Pathological examination shows evidence of liver damage. Inhalation of hydrogen selenide by workers has caused eye, nose, and respiratory irritation. Pulmonary edema is a potential toxic effect. [ACGIH] Hydrogen selenide is probably the only selenium compound that might pose a health concern in the workplace. [ATSDR ToxFAQs] Possible frostbite from contact with liquid; [NIOSH] A skin, eye, and respiratory tract irritant; May cause liver injury; May cause pulmonary edema; [ICSC] See Selenium.

Check Digit Verification of cas no
The CAS Registry Mumber 7783-07-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7783-07:
(6*7)+(5*7)+(4*8)+(3*3)+(2*0)+(1*7)=125
125 % 10 = 5
So 7783-07-5 is a valid CAS Registry Number.
