174470-20-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174470-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,4,7 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174470-20:
(8*1)+(7*7)+(6*4)+(5*4)+(4*7)+(3*0)+(2*2)+(1*0)=133
133 % 10 = 3
So 174470-20-3 is a valid CAS Registry Number.

Bates, George B.,Parker, David
, p. 267 - 270 (1996)
Synthesis of a ligand imposing tetrahedral coordination: 1,10-phenanthroline-2,9-bis(phenyl-2-acetic acid) is prepared via palladium catalysed cross-coupling of an aromatic halide and an ortho-substituted aryl stannane.
