Check Digit Verification of cas no

The CAS Registry Mumber 1394134-47-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,4,1,3 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1394134-47:
(9*1)+(8*3)+(7*9)+(6*4)+(5*1)+(4*3)+(3*4)+(2*4)+(1*7)=164
164 % 10 = 4
So 1394134-47-4 is a valid CAS Registry Number.

Microwave assisted synthesis of phenanthridinones and dihydrophenanthridines by vasicine/KO: T Bu promoted intramolecular C-H arylation

, p. 8536 - 8544 (2016/09/28)

A simple, efficient, rapid and transition metal-free methodology has been developed by utilizing vasicine (a natural product), as a catalyst for the synthesis of phenanthridinones and dihydrophenanthridines. The reaction proceeds through intramolecular C-H arylation with aryl halides in the presence of KOtBu as a base under microwave irradiation in sulfolane as a solvent. The reaction proceeds well with various aryl iodides, bromides and more remarkably with less reactive aryl chlorides for 15 minutes, providing the corresponding products in 45-90% yields.
