862658-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862658-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,6,5 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 862658-52:
(8*8)+(7*6)+(6*2)+(5*6)+(4*5)+(3*8)+(2*5)+(1*2)=204
204 % 10 = 4
So 862658-52-4 is a valid CAS Registry Number.

Total synthesis of heliophenanthrone
Dyker, Gerald,Hildebrandt, Dirk
, p. 6093 - 6096 (2007/10/03)
The total synthesis of rac-heliophenanthrone (3a) was achieved by a convergent approach, making use of a transition-metal-catalyzed domino process with an intramolecular Diels-Alder reaction at an isobenzopyrylium cation as key step.
