Check Digit Verification of cas no
The CAS Registry Mumber 34367-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,3,6 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34367-37:
(7*3)+(6*4)+(5*3)+(4*6)+(3*7)+(2*3)+(1*7)=118
118 % 10 = 8
So 34367-37-8 is a valid CAS Registry Number.

Acylation du trifluoromethoxybenzene en catalyse HF-BF3
Desbois, Michel
, p. 885 - 890 (2007/10/02)
Friedel and Crafts acylation of trifluoromethoxy- and trifluoromethyl-thiobenzene fails to give ketones in a one step synthesis if chlorinated Lewis acids (AlCl3) are used, because of halogen exchange on the -OCF3 and -SCF3 groups.The use of a fluorinated catalyst system such as HF-BF3 avoids exchange reactions and acylation occurs smoothly under mild conditions: - Low temperature and pressure - High yields (very often >90 percent) - Very high para-regioselectivity.Related reactions such as formylation or sulfonylation can also be achieved under similar conditions.
