26603-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26603-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,6,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26603-18:
(7*2)+(6*6)+(5*6)+(4*0)+(3*3)+(2*1)+(1*8)=99
99 % 10 = 9
So 26603-18-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 13168 - 13169 (2010/11/18)
A rhodium-catalyzed addition of sodium tetraarylborates to N-tosyl ketimines is described. Highly efficient asymmetric catalysis has been achieved by employing a chiral diene ligand, constructing chiral amine derivatives possessing α-tetrasubstituted carbon stereocenters with high enantioselectivity.
