4440-98-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4440-98-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4440-98:
(6*4)+(5*4)+(4*4)+(3*0)+(2*9)+(1*8)=86
86 % 10 = 6
So 4440-98-6 is a valid CAS Registry Number.

Quest for Efficient Catalysts based on Zinc tert-Butyl Peroxides for Asymmetric Epoxidation of Enones: C2- vs C1-Symmetric Auxiliaries

Raheem Keeri, Abdul,Justyniak, Iwona,Jurczak, Janusz,Lewiński, Janusz

supporting information, p. 864 - 868 (2016/04/05)

Zinc tert-butyl peroxide-based catalysts for the asymmetric epoxidation of enones using tert-butyl hydroperoxide as an oxidant have been developed. A comparative study of chiral monoanioninc N,N′-bidentate ligands, C2-symmetric bisoxazolinates and C1-symmetric enaminooxazolinates, revealed excellent performance of C1-symmetric auxiliary ligands on catalytic asymmetric epoxidation of enones (up to 96% yield, 91% ee).

Epoxidation of 1,4-diaroyl ethene derivatives in the presence of UHP or H2O2

Mahmoodi, Nosrat O.,Yazdanbakhsh, Mohammad R.,Ghanbari, Fateme

experimental part, p. 3181 - 3185 (2010/11/20)

Hydrogen peroxide (H2O2) or urea-hydrogen peroxide (UHP) in basic media react with carbon-carbon double bonds of 1,4-diaroyl ethenes to produce the corresponding epoxides. Copyright Taylor & Francis Group, LLC.
