3-(4-fluoro-phenyl)-4,5,6-triphenyl-phthalic acid-anhydride is a complex organic compound with the molecular formula C37H23F3O3. It is a derivative of phthalic anhydride, featuring a 4-fluoro-phenyl group at the 3-position and three phenyl rings attached to the 4, 5, and 6 positions. 3-(4-fluoro-phenyl)-4,5,6-triphenyl-phthalic acid-anhydride is characterized by its anhydride functional group, which is formed by the loss of a water molecule from two carboxylic acid groups. It is a white crystalline solid and is used in the synthesis of various pharmaceuticals, dyes, and other organic compounds. Due to its complex structure and fluorine substitution, it may exhibit unique chemical properties and reactivity compared to its non-fluorinated counterparts.
The CAS Registry Mumber 340-17-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 0 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 340-17: (5*3)+(4*4)+(3*0)+(2*1)+(1*7)=40 40 % 10 = 0 So 340-17-0 is a valid CAS Registry Number.
