65618-06-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65618-06-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,1 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 65618-06:
(7*6)+(6*5)+(5*6)+(4*1)+(3*8)+(2*0)+(1*6)=136
136 % 10 = 6
So 65618-06-6 is a valid CAS Registry Number.

Synthesis of substituted tryptanthrins via oxidation of isatin and its derivatives

Moskovkina,Denisenko,Kalinovskii,Stonik

, p. 1740 - 1743 (2013)

Oxidation of isatin and its 5-substituted analogs with potassium permanganate in anhydrous acetonitrile gave indolo[2,1-b]quinazoline-6,12-dione (tryptanthrin) and its 2,8-dimethyl-, 2,8-dibromo-, and 2,8-diiodo derivatives. Oxidative coupling of 5,7-dichloroisatin with isatin under analogous conditions afforded 2,4-dichloroindolo[2,1-b]quinazoline-6,12-dione, while 1,4-dichloroindolo[2,1-b]quinazoline-6,12-dione and 1,4-dichloro-8- methylindolo[2,1-b]quinazoline-6,12-dione were obtained by oxidative coupling of 4,7-dichloroisatin with isatin and 5-methylisatin, respectively.
