Check Digit Verification of cas no

The CAS Registry Mumber 18448-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,4 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18448-19:
(7*1)+(6*8)+(5*4)+(4*4)+(3*8)+(2*1)+(1*9)=126
126 % 10 = 6
So 18448-19-6 is a valid CAS Registry Number.

A new approach to the synthesis of trifluoromethylated products of the -sigmatropic rearrangement

Andreev, V. G.

, p. 1209 - 1213 (1994)

CH-acids of general formula CF3CH(X)CF3 (X = CF3, CO2R) react with 2,3-unsaturated alcohols in the presence of bases to give trifluoromethylated products of the -sigmatropic rearrangement.These reactions provide a convenient method for the synthesis of 2-alkenyl-2-trifluoromethylmalonates. - Key words: CH-acids, fluorinated; -sigmatropic rearrangement; 2-alkenyl-2-trifluoromethylmalonates.
