Check Digit Verification of cas no

The CAS Registry Mumber 1598409-43-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,8,4,0 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1598409-43:
(9*1)+(8*5)+(7*9)+(6*8)+(5*4)+(4*0)+(3*9)+(2*4)+(1*3)=218
218 % 10 = 8
So 1598409-43-8 is a valid CAS Registry Number.

Direct access to fluorene by successive C-O/C-H bond activations of 2-phenylbenzyl ester

Hirano, Masafumi,Kawazu, Sosuke,Komine, Nobuyuki

, p. 1921 - 1924 (2014/05/20)

Catalytic formation of fluorene has been achieved from 2-phenylbenzyl trifluoroacetate via successive C-O and C-H bond cleavage reactions by Pd(OAc)2/PPh3 in 97% yield. This reaction involves the oxidative addition of ester to give (carboxylato)(2-phenylbenzyl)palladium(II) species and deprotonation from the 2-phenylbenzyl group by the cleaved carboxylato group via an internal electrophilic substitution mechanism.
