99284-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99284-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,8 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99284-40:
(7*9)+(6*9)+(5*2)+(4*8)+(3*4)+(2*4)+(1*0)=179
179 % 10 = 9
So 99284-40-9 is a valid CAS Registry Number.

The Dimerisation of Some 4-Hydroxyindenes
Davis, Brian R.,Johnson, Stephen J.,Woodgate, Paul D.
, p. 2545 - 2554 (2007/10/02)
The acid-catalysed dimerisation of the indenes (1)-(5), has been studied and a number of products isolated.The structure and stereochemistry of these compounds has been established by the use of crossed dimers, 13C-labelling, and 1H and 13C n.m.r. spectroscopy.
