Check Digit Verification of cas no

The CAS Registry Mumber 105947-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,4 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105947-05:
(8*1)+(7*0)+(6*5)+(5*9)+(4*4)+(3*7)+(2*0)+(1*5)=125
125 % 10 = 5
So 105947-05-5 is a valid CAS Registry Number.

Microwave assisted rapid synthesis of phenoxazines and benzopyridoxazines

Anchan, Kavitha,Puttappa, Nagaswarupa H.,Poongavanam, Baburajan,Sarkar, Sujit Kumar

supporting information, p. 635 - 646 (2020/11/27)

A facile protocol for the synthesis of phenoxazines and benzopyridoxazines by Smiles rearrangement have been demonstrated in short reaction time under microwave irradiation. The control experiments suggest that a reaction proceeds through Smiles rearrangement followed SNAr ring closure by in situ cascade process. In our present work, both the electron donating and electron withdrawing groups were tolerant and provided a corresponding phenoxazine/benzopyridoxazine in good to moderate yields.
