α-Brom-trans-cumarsaeure, also known as α-bromocinnamic acid, is an organic compound with the chemical formula C9H7BrO2. It is a derivative of cinnamic acid, where one of the hydrogen atoms on the benzene ring is replaced by a bromine atom. This halogenated compound is a white crystalline solid that is soluble in organic solvents such as ethanol and acetone. α-Brom-trans-cumarsaeure is synthesized through the bromination of trans-cinnamic acid and is used as an intermediate in the production of various pharmaceuticals, agrochemicals, and other organic compounds. Its chemical properties include reactivity towards nucleophiles due to the presence of the electrophilic bromine atom, making it a valuable building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 90484-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,8 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90484-49:
(7*9)+(6*0)+(5*4)+(4*8)+(3*4)+(2*4)+(1*9)=144
144 % 10 = 4
So 90484-49-4 is a valid CAS Registry Number.
