1253735-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1253735-89-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,7,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1253735-89:
(9*1)+(8*2)+(7*5)+(6*3)+(5*7)+(4*3)+(3*5)+(2*8)+(1*9)=165
165 % 10 = 5
So 1253735-89-5 is a valid CAS Registry Number.

Synthesis of phenanthridinones using Cu- or Pd-mediated C[sbnd]N bond formation
Nealmongkol, Prattya,Calmes, Jordan,Ruchirawat, Somsak,Thasana, Nopporn
, p. 735 - 741 (2017)
The chemoselective synthesis of phenanthridinones was studied using copper(I)- and palladium(II)-catalyzed C[sbnd]N bond formation with various bases, ligands, and solvents. Phenanthridinones were obtained from 2-halobiarylcarboxylates and amines in a one
