1,2,3-trimethyl-4,5-diphenyl-cyclopentadiene is a complex organic compound characterized by a cyclopentadiene ring structure, which is a five-membered ring with alternating double bonds. The molecule features three methyl groups (CH3) attached to the 1st, 2nd, and 3rd carbon atoms of the ring, and two phenyl groups (C6H5) bonded to the 4th and 5th carbon atoms. This arrangement of substituents gives the compound unique chemical and physical properties, making it a potential candidate for various applications in the fields of organic chemistry and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 4916-75-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4916-75:
(6*4)+(5*9)+(4*1)+(3*6)+(2*7)+(1*5)=110
110 % 10 = 0
So 4916-75-0 is a valid CAS Registry Number.
