22743-02-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22743-02-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,7,4 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22743-02:
(7*2)+(6*2)+(5*7)+(4*4)+(3*3)+(2*0)+(1*2)=88
88 % 10 = 8
So 22743-02-8 is a valid CAS Registry Number.

Alkylation of 1H-benz[de]isoquinoline-1,3(2H)dione and benz[cd]indol-2(1H)one under conditions of phase-transfer catalysis
Anikin,Krasnova,Kupriyan
, p. 486 - 489 (2007/10/03)
The possibility of phase-transfer N-alkylation of 1H-benz[de]isoquinoline-1,3(2H)-dione (naphthalimide) and benz[cd]indol-2(1H)-one (naphthostyril), catalyzed with tetraalkylammonium nitrates, was studied.
