681433-46-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 681433-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,4,3 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 681433-46:
(8*6)+(7*8)+(6*1)+(5*4)+(4*3)+(3*3)+(2*4)+(1*6)=165
165 % 10 = 5
So 681433-46-5 is a valid CAS Registry Number.

Efficient Asymmetric Synthesis of 2,6-Disubstituted 2H-Dihydropyrans via a Catalytic Hetero-Diels-Alder/Allylboration Sequence

Deligny, Michael,Carreaux, Francois,Toupet, Loic,Carboni, Bertrand

, p. 1215 - 1219 (2007/10/03)

[4 + 2] Cycloaddition of (E)-3-borylacrolein 1 with ethyl vinyl ether, catalysed by chromium complex (1R,25) or (15,2R) 2, led to the corresponding cycloadducts with high diastereo- and enantioselectivities. Further reaction with aldehydes offers an attractive asymmetric route to synthetically useful substituted 3,4-dihydro-2H-pyrans.
