28115-07-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28115-07-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,1 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28115-07:
(7*2)+(6*8)+(5*1)+(4*1)+(3*5)+(2*0)+(1*7)=93
93 % 10 = 3
So 28115-07-3 is a valid CAS Registry Number.

Synergistic interplay of a non-heme iron catalyst and amino acid coligands in H2O2 activation for asymmetric epoxidation of α-alkyl-substituted styrenes

Cuss, Olaf,Ribas, Xavi,Lloret-Fillol, Julio,Costas, Miquel

, p. 2729 - 2733 (2015)

Highly enantioselective epoxidation of α-substituted styrenes with aqueous H2O2 is described by using a chiral iron complex as the catalyst and N-protected amino acids (AAs) as coligands. The amino acids synergistically cooperate with the iron center in promoting an efficient activation of H2O2 to catalyze epoxidation of this challenging class of substrates with good yields and stereoselectivities (up to 97% ee) in short reaction times.
