61656-02-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 61656-02-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,6,5 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61656-02:
(7*6)+(6*1)+(5*6)+(4*5)+(3*6)+(2*0)+(1*2)=118
118 % 10 = 8
So 61656-02-8 is a valid CAS Registry Number.

Elimination kinetics and toxicity of 2,3,7,8-tetrachlorothianthren, a thio analogue of 2,3,7,8-TCDD

Weber, R.,Hagenmaier, H.,Schrenk, D.

, p. 2635 - 2642 (1998)

In comparison to the polychlorinated dibenzo-p-dioxins (PCDD) informations on their thio analogues the polychlorinated thianthrens (PCTA) are very limited. In this study we investigated the kinetics and toxicity of 2,3,7,8-tetrachlorothianthren (TCTA), the analogue of the most toxic PCDD congener 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). It was found that TCTA is rapidly eliminated in mouse liver homogenate fortified with an NADPH-regenerating system suggesting rapid metabolic degradation by liver monooxygenases. Furthermore, TCTA was rapidly eliminated from mouse liver and whole body. In accordance with this rapid elimination, a weekly dosage of 1 mg TCTA per kg body weight (i.p.) over six weeks did not result in weight loss or other signs of overt toxicity in male mice. In rat hepatocytes in primary culture, TCTA was active as inducer of dioxin receptor-regulated cytochrome P4501A1 activity measured as 7-ethoxyresorufin O-deethylase (EROD). The relative inducing potency was about 0.0001 in comparison to TCDD. In spite of this molecular effects, the rapid elimination both in vitro and in vivo argues against a consideration of a TCDD equivalency factor for TCTA.

The study on UV-degradation dynamics of 2,3,7,8-tetrachlorodibenzo-p-dioxin and its analogues

Qin, Zhaohai

, p. 91 - 97 (2007/10/03)

A study on UV-degradation dynamics of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) and its analogues 2,3,7,8-tetrachlorophenoxthin (2,3,7,8-TCPT) and 2,3,7,8-tetrachlorothianthrene (2,3,7,8-TCTR) in solvents CHCl3 and CCl4 was completed. The results indicated that they were degradated by UV in different way in different solvent. The degradation of 2,3,7,8-TCDD and 2,3,7,8-TCPT are pseudo-first-order reactions in CHCl3, but complex reactions in CCl4; the degradation of 2,3,7,8-TCTR is a zero-order reaction in CHCl3, but a pseudo-first-order reaction in CCl4. All of the three compounds disappeared in CCl4 much faster than in CHCl3 under 254 nm UV-irradiation.
