1159-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1159-93:
(6*1)+(5*1)+(4*5)+(3*9)+(2*9)+(1*3)=79
79 % 10 = 9
So 1159-93-9 is a valid CAS Registry Number.

Palladium-mediated approach to dibenzo[b,e][1,4]diazepines and benzopyrido-analogues. An efficient synthesis of tarpane

An original synthetic route toward dibenzo[b,e][1,4]diazepin-11-ones and analogues pyridobenzodiazepinones has been developed. The method relies upon an intramolecular amination process between an (hetero)aryl halide and the appropriate aniline moiety. Graphical Abstract.
