69780-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69780-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,7,8 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69780-68:
(7*6)+(6*9)+(5*7)+(4*8)+(3*0)+(2*6)+(1*8)=183
183 % 10 = 3
So 69780-68-3 is a valid CAS Registry Number.

The reaction of PhI=NTs with sulfoxides in the presence of catalytic amounts of CuOTf afforded the corresponding N-tosylsulfoximines in high yield. The use of enantiomerically pure sulfoxides allowed stereoselective access to N-tosylsulfoximines with comp
