620622-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 620622-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,6,2 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 620622-40:
(8*6)+(7*2)+(6*0)+(5*6)+(4*2)+(3*2)+(2*4)+(1*0)=114
114 % 10 = 4
So 620622-40-4 is a valid CAS Registry Number.

Dynamic kinetic asymmetric cycloadditions of isocyanates to vinylaziridines
Trost, Barry M.,Fandrick, Daniel R.
, p. 11836 - 11837 (2007/10/03)
The first examples of the use of racemic vinylaziridines in a Pd-catalyzed dynamic kinetic asymmetric transformation have been examined. Optimization studies of the Pd-catalyzed addition of vinylaziridines to isocyanates revealed that the chiral ligand be
