213689-90-8 Usage
General Description
The chemical compound (E)-3-(diethylamino)-1-(2-hydroxy-5-methylphenyl)prop-2-en-1-one, also known as "DEET," is a widely used insect repellent. It is often applied topically to the skin or clothing to protect against insect bites, particularly from mosquitoes, ticks, and flies. DEET works by masking the scent of carbon dioxide and other chemicals emitted by the body, making it harder for insects to locate and bite the user. Its effectiveness against a wide range of insects, as well as its relatively low toxicity to humans, has made it a popular choice for insect repellent products. However, there is some concern about its potential health and environmental effects, so it is important to use DEET according to the manufacturer's instructions.
Check Digit Verification of cas no
The CAS Registry Mumber 213689-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,6,8 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 213689-90:
(8*2)+(7*1)+(6*3)+(5*6)+(4*8)+(3*9)+(2*9)+(1*0)=148
148 % 10 = 8
So 213689-90-8 is a valid CAS Registry Number.
