Check Digit Verification of cas no

The CAS Registry Mumber 1427219-07-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,1 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1427219-07:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*1)+(3*9)+(2*0)+(1*7)=145
145 % 10 = 5
So 1427219-07-5 is a valid CAS Registry Number.

Enantioselective Michael reaction of anthrone catalyzed by chiral tetraoxacalix[2]arene[2]triazine derivatives

Genc, Hayriye Nevin

, p. 21063 - 21069 (2019)

A highly enantioselective Michael addition reaction of anthrone with nitroalkenes by chiral tetraoxacalix[2]arene[2]triazine catalysts was investigated as a novel topic. The stereoselective conversion progressed smoothly by employing 10 mol% of the catalyst and afforded the corresponding Michael adducts with acceptable to high enantioselectivities (up to 97% ee) and very high yields (up to 96%).
