It is characterized by a chloromethyl group (-CH2Cl) attached to a central carbon atom, which is bonded to two phenyl rings and a 4-phenyl-1-naphthyl group. This molecule is a derivative of triphenylmethane, with a chlorine atom replacing one of the hydrogen atoms on the central carbon. It is a white crystalline solid and is used in the synthesis of various organic compounds, particularly in the pharmaceutical and chemical industries. Due to its complex structure, it is often used as an intermediate in the preparation of dyes, pigments, and other specialty chemicals.
The CAS Registry Mumber 1674-20-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1674-20: (6*1)+(5*6)+(4*7)+(3*4)+(2*2)+(1*0)=80 80 % 10 = 0 So 1674-20-0 is a valid CAS Registry Number.
