Check Digit Verification of cas no

The CAS Registry Mumber 299-45-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 299-45:
(5*2)+(4*9)+(3*9)+(2*4)+(1*5)=86
86 % 10 = 6
So 299-45-6 is a valid CAS Registry Number.

Synthesis and anticholinesterase activity of some new fluorogenic analogues of organophosphorus nerve agents

Timperley, Christopher M.,Casey, Krystal E.,Notman, Stuart,Sellers, David J.,Williams, Nancy E.,Williams, Nichola H.,Williams, Gareth R.

, p. 1554 - 1563 (2008/09/18)

Eighteen new fluorogenic analogues of organophosphorus nerve agents were synthesised and characterised. They included analogues of tabun, sarin, cyclosarin, soman, VX, and Russian VX, with the 7-oxy-4-methylcoumarin or 7-oxy-4-(trifluoromethyl)coumarin leaving group. These analogues inhibited acetylcholinesterase (AChE) effectively in vitro and therefore have potential as tools for the identification of novel organophosphatases in biological systems. Analogues of VX and Russian VX with the 7-amino-4-methylcoumarin group, although poor AChE inhibitors, may have utility for screening enzyme libraries for phosphoramidases capable of cleaving P-N bonds.

Synthesis of (diethyl-d10) coumaphos and related compounds

Kochansky, Jan

, p. 2826 - 2828 (2007/10/03)

Two deuterated insecticides were prepared for use as internal standards for gas-liquid chromatographic-mass spectrometric analyses. Diethyl chlorothiophosphate-d10 was prepared by reaction of ethanol-d6 with P2S5 to give labeled diethyldithiophosphoric acid, followed by chlorination. Treatment of the acid chloride with 3-chloro-4-methyl-7-hydroxycoumarin and potassium carbonate in acetone at reflux gave labeled coumaphos. An analogous reaction with 4-methyl-7-hydroxycoumarin gave labeled potasan, and the technique should be usable for synthesis of labeled forms of other dialkyl thiophosphate insecticides.
