923603-92-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 923603-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,6,0 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 923603-92:
(8*9)+(7*2)+(6*3)+(5*6)+(4*0)+(3*3)+(2*9)+(1*2)=163
163 % 10 = 3
So 923603-92-3 is a valid CAS Registry Number.

Synthesis of fused heterocycles with a benzazepinone moiety via intramolecular Heck coupling
Joucla, Lionel,Putey, Aurélien,Joseph, Beno?t
, p. 8177 - 8179 (2005)
The preparation of fused heterocycles with a benzazepinone moiety was realised via an intramolecular Heck coupling reaction either at position 2 or at position 3 of the heterocyclic system. This method allowed the synthesis of the pyrrolo[2,3-c]azepinone
