Toxicity evaluation
The acute oral LD50 value in rats was reported as 1.15 g/kg (0.58-1.72 g/kg) and the acute dermal LD50 value in rabbits as > 5 g/kg (Moreno, 1974). In mice, the LD50 of essential oils, including tansy oil, was 3-5 mg; no conjunctivitis was produced by a 1% emulsion of tansy oil given as eye drops daily for 1 wk (Rotmistrov, Gendenshtein & Matveenko, 1957).
Check Digit Verification of cas no
The CAS Registry Mumber 8016-87-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,1 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 8016-87:
(6*8)+(5*0)+(4*1)+(3*6)+(2*8)+(1*7)=93
93 % 10 = 3
So 8016-87-3 is a valid CAS Registry Number.
