28164-92-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28164-92-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,6 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28164-92:
(7*2)+(6*8)+(5*1)+(4*6)+(3*4)+(2*9)+(1*2)=123
123 % 10 = 3
So 28164-92-3 is a valid CAS Registry Number.

Synergistic catalysis of anthrone Dels-Ader reactions
Harrison, Roy,Rickborn, Bruce
, p. 1711 - 1713 (2002)
Matrix presented The combination of an amine base and Lewis acid (Li+) leads to synergistic catalysis of the Diels-Alder reaction of anthrone with methyl crotonate and some other less reactive dienophiles. These cycloadditions either do not occ
