213479-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213479-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,4,7 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213479-69:
(8*2)+(7*1)+(6*3)+(5*4)+(4*7)+(3*9)+(2*6)+(1*9)=137
137 % 10 = 7
So 213479-69-7 is a valid CAS Registry Number.

An efficient synthesis of dihydroxyfluorenones via in situ Pd(0)-catalyzed cross-coupling
Ciske, Fred L.,Jones Jr., Winton D.
, p. 1195 - 1198 (1998)
All six dimethoxyfluorenones 6a-f and dihydroxyfluorenones 7a-f, wherein substitution occurs at only one aromatic ring, were conveniently prepared by palladium(0)-catalyzed cross-coupling reactions of aryl bromides/triflates 2a-e with in situ generated ar
