1-Bromo-4-chloro-2,5-difluorobenzene is a chemical compound with the molecular formula C6H2BrClF2. It is a colorless to light yellow liquid that is commonly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It is also used as a building block in the production of specialty chemicals and materials. The compound is flammable and should be handled with caution, as it may cause skin and eye irritation upon contact. 1-Bromo-4-chloro-2,5-difluorobenzene is typically stored and transported in sealed containers to prevent exposure to air and moisture, which could lead to degradation of the compound.
Check Digit Verification of cas no
The CAS Registry Mumber 172921-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,2 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 172921-33:
(8*1)+(7*7)+(6*2)+(5*9)+(4*2)+(3*1)+(2*3)+(1*3)=134
134 % 10 = 4
So 172921-33-4 is a valid CAS Registry Number.
