Check Digit Verification of cas no

The CAS Registry Mumber 685555-22-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,5,5 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 685555-22:
(8*6)+(7*8)+(6*5)+(5*5)+(4*5)+(3*5)+(2*2)+(1*2)=200
200 % 10 = 0
So 685555-22-0 is a valid CAS Registry Number.

Palladium-catalyzed oxidative arylation of chromones via a double C-H activation: An expedient approach to flavones

Kim, Ko Hoon,Lee, Hyun Seung,Kim, Se Hee,Kim, Jae Nyoung

, p. 2761 - 2764 (2012)

A palladium-catalyzed oxidative arylation of chromones was examined. A regioselective 2-arylation of chromone was carried out via a double C-H activation process. The procedure provided an expedient approach for the preparation of flavone derivatives.
