Check Digit Verification of cas no

The CAS Registry Mumber 198141-12-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,1,4 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 198141-12:
(8*1)+(7*9)+(6*8)+(5*1)+(4*4)+(3*1)+(2*1)+(1*2)=147
147 % 10 = 7
So 198141-12-7 is a valid CAS Registry Number.

Rapid and efficient microwave-assisted synthesis of 4-, 5-, 6- and 7-azaindoles

Lachance, Nicolas,April, Myriam,Joly, Marc-Andre

, p. 2571 - 2577 (2007/10/03)

Under microwave irradiation conditions, the imines/enamines formed between aminopyridines and ketones are converted in moderate to good yields to the corresponding 4-, 5-, 6- or 7-azaindoles via the Hegedus-Mori-Heck reaction (intramolecular Heck reaction

Palladium-catalyzed synthesis of 1,2-dihydro-4(3H)-carbazolones. Formal total synthesis of murrayaquinone A

Scott, Tricia L.,S?derberg, Bj?rn C. G.

, p. 6323 - 6332 (2007/10/03)

Two sequential palladium-catalyzed reactions are the key steps in a novel synthetic route to 1,2-dihydro-4(3H)-carbazolones. The steps are an intermolecular Stille cross-coupling followed by a reductive N-heteroannulation. A formal total synthesis of murrayaquinone A, employing this sequence, is reported.
