372956-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 372956-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,2,9,5 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 372956-43:
(8*3)+(7*7)+(6*2)+(5*9)+(4*5)+(3*6)+(2*4)+(1*3)=179
179 % 10 = 9
So 372956-43-9 is a valid CAS Registry Number.

Efficient access to 3-alkyl-trifluoromethylbenzenes using Kumada's coupling reaction
Roques, Nicolas,Saint-Jalmes, Laurent
, p. 3375 - 3378 (2006)
3-Alkyl-trifluoromethylbenzenes are obtained in good yields by Kumada's coupling reaction between methyl or ethyl magnesium halide and 3-bromo-trifluoromethylbenzene derivatives in the presence of Ni-Xantphos catalyst.
