552839-00-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 552839-00-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,8,3 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 552839-00:
(8*5)+(7*5)+(6*2)+(5*8)+(4*3)+(3*9)+(2*0)+(1*0)=166
166 % 10 = 6
So 552839-00-6 is a valid CAS Registry Number.

Carbon-carbon bond formation in palladium(II)-catalyzed allylic oxidation: A novel oxidative carbocyclization of allene-substituted olefins
Franzen, Johan,Baeckvall, Jan-E.
, p. 6056 - 6057 (2003)
A new efficient palladium(II)-catalyzed oxidative carbocyclization has been developed. It was found that allene-substituted olefins 1 cyclized in the presence of 1 mol % Pd(O2CCF3)2 and p-benzoquinone (2 equiv) to give bic
