216663-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216663-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,6,6 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 216663-83:
(8*2)+(7*1)+(6*6)+(5*6)+(4*6)+(3*3)+(2*8)+(1*3)=141
141 % 10 = 1
So 216663-83-1 is a valid CAS Registry Number.

On the efficacy of propeller-shaped, C3-symmetric triarylphosphines in asymmetric catalysis
Powell, Mark T.,Porte, Alexander M.,Burgess, Kevin
, p. 2161 - 2162 (1998)
Ligand sets 1 and 2 were prepared and examined for evidence of C3-symmetric propeller-shaped conformations in solution, and for their ability to induce enantioselectivity in an allylation reaction.
