186134-88-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 186134-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,1,3 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 186134-88:
(8*1)+(7*8)+(6*6)+(5*1)+(4*3)+(3*4)+(2*8)+(1*8)=153
153 % 10 = 3
So 186134-88-3 is a valid CAS Registry Number.

Thermal addition reaction of aroylketene with ethyl vinyl ether: Aromatic substituent effect on aroylketene reactivity

Toda, Jun,Saitoh, Toshiaki,Oyama, Taichi,Horiguchi, Yoshie,Sano, Takehiro

, p. 2457 - 2464 (2007/10/03)

A series of aroylketenes (2) generated by thermolysis of 5-aryl-2,3-dihydrofuran-2,3-diones (1) reacted with ethyl vinyl ether under a thermal condition to give 2,3-dihydro-4H-pyran-4-ones (3) and/or 4H-pyran-4-ones (4). In this reaction the electron withdrawing substituent (NO2, Cl) introduced into the aryl part enhanced the ketene reactivity (2b-e), while the electron donating one (OMe) did not affect its reactivity (2f-g) in a significant extent. The heteroaroylketenes (2h) and (2i) showed a fairly good reactivity.
