Check Digit Verification of cas no

The CAS Registry Mumber 1372788-44-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,7,8 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1372788-44:
(9*1)+(8*3)+(7*7)+(6*2)+(5*7)+(4*8)+(3*8)+(2*4)+(1*4)=197
197 % 10 = 7
So 1372788-44-7 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.
