133390-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133390-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,9 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133390-97:
(8*1)+(7*3)+(6*3)+(5*3)+(4*9)+(3*0)+(2*9)+(1*7)=123
123 % 10 = 3
So 133390-97-3 is a valid CAS Registry Number.

Nitroolefins in one-flask, tandem. A+B+C coupling reactions producing heterocycles
Posner, Gary H.,David Crouch
, p. 7509 - 7530 (2007/10/02)
Nitroolefins are shown to be effective Michael acceptor B units in sequential, convenient, multi-gram scale A+B+C coupling in one reaction vessel to produce nitroalkane intermediates that are converted into oxygen and nitrogen heterocycles. The sequence i
