α-Chlormethan-sulfonyl-styrol, also known as α-chloroacetophenones, is a class of chemicals that are derivatives of acetophenone. These compounds are characterized by the presence of a chloromethyl group (-CH2Cl) and a sulfonyl group (-SO2) attached to the aromatic ring. They are synthesized by reacting acetophenone with chlorosulfonic acid, followed by the addition of a suitable nucleophile. α-Chlormethan-sulfonyl-styrol compounds have various applications in the chemical industry, particularly in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Due to their reactivity, they are often used as intermediates in the preparation of various organic compounds, such as dyes, pigments, and polymers. However, they are also known to be toxic and should be handled with care due to their potential health and environmental risks.
The CAS Registry Mumber 1854-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 4 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1854-76: (6*1)+(5*8)+(4*5)+(3*4)+(2*7)+(1*6)=98 98 % 10 = 8 So 1854-76-8 is a valid CAS Registry Number.
