108802-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108802-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,0 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 108802-89:
(8*1)+(7*0)+(6*8)+(5*8)+(4*0)+(3*2)+(2*8)+(1*9)=127
127 % 10 = 7
So 108802-89-7 is a valid CAS Registry Number.

DOUBLY-DESTABILIZED CARBOCATIONS. DETECTION AND TRAPPING OF ARYL-BISCARBOETHOXYCARBOCATIONS.
Fletcher, David,Ablenas, Fred J.,Hopkinson, Alan C.,Lee-Ruff, Edward
, p. 4853 - 4856 (1986)
Diethyl bromo(aryl)malonates undergo ionization in superacids at -78 deg C to give the corresponding cations.These doubly destabilized cations can be trapped with benzene or toluene to give the corresponding Friedel-Crafts adducts.
