Check Digit Verification of cas no

The CAS Registry Mumber 81116-48-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,1 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81116-48:
(7*8)+(6*1)+(5*1)+(4*1)+(3*6)+(2*4)+(1*8)=105
105 % 10 = 5
So 81116-48-5 is a valid CAS Registry Number.

93. Aromatic Nucleophilic Substitution. Part 2. Preparation of Novel 3-Substituted Xanthone and Thioxanthone Derivatives

Fischer, Walter,Kvita, Vratislav

, p. 854 - 859 (1985)

The novel 3-nitro-9-oxo-9H-xanthene- and 3-nitro-9-oxo-9H-thioxanthene-1-carboxylic acids 2a-d were prepared by intramolecular acylation of 3-aryloxy- and 3-arylthio-5-nitrophthalic anhydrides 1 (Scheme).The 3-nitro group was readily substituted by O- and

Thioxanthonecarboxylic acids and thioxanthonecarboxylic acid derivatives

-

, (2008/06/13)

Novel thioxanthonecarboxylic acids and thioxanthonecarboxylic acid derivatives of the formula I STR1 in which Y is --COOH, --CO-halogen, --CN or a carboxylic acid ester, thioester or amide group and X, Z and W are as defined in the patent claim, are described. The compounds of the formula I in which Y is other than --CO--halogen are suitable as sensitizers for photo-crosslinkable polymers or as initiators for photo-polymerization of ethylenically unsaturated compounds or for photo-chemical crosslinking of polyolefins. The acid halides of the formula I are starting materials for the preparation of the corresponding nitriles and carboxylic acid esters, thioesters and amides.
