Check Digit Verification of cas no

The CAS Registry Mumber 20033-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,3 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20033-18:
(7*2)+(6*0)+(5*0)+(4*3)+(3*3)+(2*1)+(1*8)=45
45 % 10 = 5
So 20033-18-5 is a valid CAS Registry Number.

An Efficient Synthesis of Benzofluorenes Via α-Alkoxycarbonyldiarylmethyl Cations

Hopkinson, A. C.,Lee-Ruff, E.,Maleki, M.

, p. 366 - 371 (1986)

Rearrangement of α-alkoxycarbonyldiarylmethyl cations lead to 9-fluorenecarboxylic esters.Decarboxylation of these esters generates the fluorene derivatives 9a-f.The precursors to the cations are the α-hydroxyesters 6a-g.This conversion constitutes a facile synthesis of benzofluorenes.
