79644-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79644-43-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,6,4 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79644-43:
(7*7)+(6*9)+(5*6)+(4*4)+(3*4)+(2*4)+(1*3)=172
172 % 10 = 2
So 79644-43-2 is a valid CAS Registry Number.

Enantioselective rare-earth catalyzed quinone Diels-Alder reactions
Evans, David A.,Wu, Jimmy
, p. 10162 - 10163 (2003)
A highly enantioselective, quinone Diels-Alder reaction catalyzed by chiral samarium and gadolinium pyridyl-bis(oxazoline) (pybox) complexes has been developed. The reaction scope has been extended to include three quinones and five dienes, all of which e
