1--tetraphenyl-cyclopentadienol-(1) is a complex organic compound characterized by a cyclopentadienol core, which is a five-membered ring with alternating double bonds. This core is adorned with four phenyl groups, which are benzene rings, providing the molecule with significant steric bulk and aromatic character. The propin-(2)-yl group, which is a propargyl group (a three-carbon chain with a triple bond at one end), is attached to the cyclopentadienol ring, adding to the molecule's complexity and potential reactivity. 1--tetraphenyl-cyclopentadienol-(1) is likely to be of interest in organic synthesis and materials science due to its unique structure and the possibility of forming various derivatives through chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 4909-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4909-27:
(6*4)+(5*9)+(4*0)+(3*9)+(2*2)+(1*7)=107
107 % 10 = 7
So 4909-27-7 is a valid CAS Registry Number.
