Check Digit Verification of cas no

The CAS Registry Mumber 103204-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,0 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103204-07:
(8*1)+(7*0)+(6*3)+(5*2)+(4*0)+(3*4)+(2*0)+(1*7)=55
55 % 10 = 5
So 103204-07-5 is a valid CAS Registry Number.

Palladium-Catalyzed, Norbornene-Mediated, ortho-Amination ipso-Amidation: Sequential C-N Bond Formation

Whyte, Andrew,Olson, Maxwell E.,Lautens, Mark

, p. 345 - 348 (2018)

A palladium-catalyzed, norbornene-mediated ortho- and ipso-C-N bond-forming Catellani reaction is reported. This reaction proceeds through a sequential intermolecular amination followed by intramolecular cyclization of a tethered amide. The products, ortho-aminated dihydroquinolinones, were generated in moderate to good yields and are present in bioactive molecules. This work highlights the challenge of competing intra- vs intermolecular palladium-catalyzed processes.
