Check Digit Verification of cas no
The CAS Registry Mumber 14203-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14203-19:
(7*1)+(6*4)+(5*2)+(4*0)+(3*3)+(2*1)+(1*9)=61
61 % 10 = 1
So 14203-19-1 is a valid CAS Registry Number.

New Enzyme Models of Chloroperoxidase: Improved Stability and Catalytic Efficiency of Iron Porphyrinates Containing a Thiolato Ligand
Wagenknecht, Hans-Achim,Claude, Cécile,Woggon, Wolf-Dietrich
, p. 1506 - 1520 (2007/10/03)
The heme-thiolate protein chloroperoxidase (CPO) catalyzes the chlorination of activated C-H bonds. A reaction mechanism is proposed for this enzymatic transformation (Scheme 1), and a new iron(III) porphyrinate complex 13 is synthesized containing pentafluorophenyl groups at two meso-positions and a thiophenolato ligand coordinating to the Fe-atom (Schemes 2 and 3). Due to the presence of the electron-withdrawing substituents, the catalyst 13 is appreciably resistant to oxidants (HOCl) and chlorinates, e.g., monochlorodimedone (5), with turnover numbers up to 1530. The redox potential of 13, E0 = - 134 mV, and the Soret band (λmax 448 nm) of the CO adduct of the reduced state of 13 are close to the corresponding values of the enzyme CPO.
