Check Digit Verification of cas no

The CAS Registry Mumber 133513-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,1 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133513-17:
(8*1)+(7*3)+(6*3)+(5*5)+(4*1)+(3*3)+(2*1)+(1*7)=94
94 % 10 = 4
So 133513-17-4 is a valid CAS Registry Number.

Sulfur analogues of polychlorinated dibenzo-p-dioxins, dibenzofurans and diphenyl ethers as inducers of CYP1A1 in mouse hepatoma cell culture and structure-activity relationships

Kopponen,Sinkkonen,Poso,Gynther,Karenlampi

, p. 1543 - 1548 (1994)

Three sulfur-containing compounds, 2,3,7,8-tetrachlorothianthrene (TCTA), 2,3,7,8-tetrachlorodibenzothiophene (TCDT), and 3,3',4,4'- tetrachlorodiphenyl sulfide (TCDPS), were analyzed for their CYP1A1-inducing potencies - measured as aryl hydrocarbon hydroxylase (AHH) and 7- ethoxyresorufin O-deethylase (EROD) activities - in mouse hepatoma cell culture Hepa-1. Marked differences in the induction potencies were observed among the three compounds studied and between 2,3,7,8-tetrachlorodibenzo-p- dioxin (TCDD) and its sulfur analogue. The estimated EC50 values for TCDD, TCTA, and TCDT were about 8 pM, 700 pM, and 7.5 nM, respectively. TCDPS did not elicit any AHH/EROD induction. Comparative molecular field analysis (CoMFA) was not able to predict correctly the biological potency of TCTA and TCDT. The most important reason for the poor performance of the model may be the positive point charge of sulfur in TCTA and TCDT.
