Check Digit Verification of cas no

The CAS Registry Mumber 129006-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,0 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129006-48:
(8*1)+(7*2)+(6*9)+(5*0)+(4*0)+(3*6)+(2*4)+(1*8)=110
110 % 10 = 0
So 129006-48-0 is a valid CAS Registry Number.

CATALYTIC ACTIVITY AND CHEMICAL STABILITY OF PERHALOGENATED Mn(III)-TETRAARYLPORPHYRINS IN ALKENE EPOXIDATIONS

Banfi, Stefano,Mandelli, Roberta,Montanari, Fernando,Quici, Silvio

, p. 409 - 415 (2007/10/02)

Structural factors, which govern the chemical stability of metallo-tetraaryl porphyrins, were investigated in CH2Cl2/H2O two-phase alkene epoxidations promoted by aqueous NaOCl or 30percent H2O2. In contrast to recent literature reports, the perhalogenati

Highly selective bromination of tetramesitylporphyrin: An easy access to robust metalloporphyrins, M-Br8TMP and M-Br8TMPS

Hoffmann,Labat,Robert,Meunier

, p. 1991 - 1994 (2007/10/02)

The N-bromosuccinimide bromination of the zinc derivative of meso-tetramesitylporphyrin, Zn(TMP), in methanol at reflux in air, gives the corresponding (β-pyrrole)octabromo derivative, meso-tetramesityl-β-octabromoporphyrinatozinc, Zn(Br8TMP), in high yield (60-75%). Furthermore, the sulfonation by oleum of the metal-free ligand gives the persulfonated porphyrin, meso-tetrakis(3,5-disulfonatomesityl)-β-octabromoporphyrin, Br8 TMPSH2 (70-75%). These robust manganese and iron derivatives are efficient catalysts in oxygen atom or electron transfer reactions.
