Check Digit Verification of cas no

The CAS Registry Mumber 117260-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,6 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117260-08:
(8*1)+(7*1)+(6*7)+(5*2)+(4*6)+(3*0)+(2*0)+(1*8)=99
99 % 10 = 9
So 117260-08-9 is a valid CAS Registry Number.

Synthesis of o -(dimethylamino)aryl ketones, acridones, acridinium salts, and 1 H -indazoles by the reaction of hydrazones and arynes

Dubrovskiy, Anton V.,Larock, Richard C.

, p. 11232 - 11256 (2013/02/23)

A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in good to excellent yields.
