Check Digit Verification of cas no

The CAS Registry Mumber 172989-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,8 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172989-48:
(8*1)+(7*7)+(6*2)+(5*9)+(4*8)+(3*9)+(2*4)+(1*8)=189
189 % 10 = 9
So 172989-48-9 is a valid CAS Registry Number.

Electronic Effect of Ligands on the Stability of Nickel-Ketene Complexes

Al, Noman,Stolley, Ryan M.,Staudaher, Nicholas D.,Vanderlinden, Ryan T.,Louie, Janis

, p. 3750 - 3755 (2018)

Electronically variant (dppf)Ni(ketene) complexes were synthesized and characterized to perform kinetic analysis on their decomposition through a decarbonylation/disproportion process to Ni-CO complexes and alkenes. Ligands containing electron-donating groups stabilized such complexes, whereas an electron-withdrawing group was found to destabilize them. Hammett analysis on the decomposition reaction revealed the buildup of negative charges in the rate-determining step, which corroborates past computational models.
