140604-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140604-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140604-90:
(8*1)+(7*4)+(6*0)+(5*6)+(4*0)+(3*4)+(2*9)+(1*0)=96
96 % 10 = 6
So 140604-90-6 is a valid CAS Registry Number.

trifuso-Centrotetraindan - Two Synthesis of a New Centropolyindan
Kuck, Dietmar,Seifert, Monika
, p. 1461 - 1470 (2007/10/02)
Two independent syntheses of the new centrotetraindan 2, a "trifuso", Cs-symmetrical isomer of fenestrindan 1, are described.The first approach is based on the "endo"-phenyldiindanone 7, which is converted into 2 by benzylation to ketone 8 and
