1226803-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1226803-92-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,8,0 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1226803-92:
(9*1)+(8*2)+(7*2)+(6*6)+(5*8)+(4*0)+(3*3)+(2*9)+(1*2)=144
144 % 10 = 4
So 1226803-92-4 is a valid CAS Registry Number.

Organocatalytic asymmetric Diels-Alder reaction of furan under high pressure
Mimoto, Akiko,Nakano, Keiji,Ichikawa, Yoshiyasu,Kotsuki, Hiyoshizo
scheme or table, p. 799 - 804 (2010/10/05)
A new method for the asymmetric Diels-Alder reaction between furan and acrolein has been developed through the combined use of chiral organocatalysts and high pressure (yield up to 91%; endo-adduct up to 19% ee, exo-adduct up to 26% ee).
