2643-39-2 Usage
General Description
[(2-bromo-2-phenylethyl)sulfonyl]benzene, also known as Bromophenylbenzenesulfonate, is a chemical compound with the molecular formula C14H11BrO2S. It is a sulfonyl compound with a benzene ring attached to a sulfonyl group, which in turn is linked to a 2-bromo-2-phenylethyl group. [(2-bromo-2-phenylethyl)sulfonyl]benzene is primarily used as a pharmaceutical intermediate for the synthesis of other organic compounds. It is also used in the production of dyes, fragrances, and other organic chemicals. Additionally, it has potential applications in the field of medicinal chemistry and drug development. Bromophenylbenzenesulfonate is a white to off-white solid with a melting point of 102-103°C and is considered hazardous if inhaled, in contact with skin, or if swallowed, and should be handled with proper safety precautions.
Check Digit Verification of cas no
The CAS Registry Mumber 2643-39-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,4 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2643-39:
(6*2)+(5*6)+(4*4)+(3*3)+(2*3)+(1*9)=82
82 % 10 = 2
So 2643-39-2 is a valid CAS Registry Number.
