897655-92-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 897655-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,7,6,5 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 897655-92:
(8*8)+(7*9)+(6*7)+(5*6)+(4*5)+(3*5)+(2*9)+(1*2)=254
254 % 10 = 4
So 897655-92-4 is a valid CAS Registry Number.

Synthesis of bowl-shaped polycyclic aromatic hydrocarbons via palladium-catalyzed intramolecular arylation reactions

Kim, Daehwan,Petersen, Jeffrey L.,Wang, Kung K.

, p. 2313 - 2316 (2007/10/03)

Treatment of the benzannulated enediyne 11 with potassium tert-butoxide in refluxing toluene for 12 h produced 15 via a cascade sequence of cyclization reactions. Two subsequent palladium-catalyzed intramolecular arylation reactions then afforded the bowl
