Check Digit Verification of cas no

The CAS Registry Mumber 288087-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,0,8 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 288087-83:
(8*2)+(7*8)+(6*8)+(5*0)+(4*8)+(3*7)+(2*8)+(1*3)=192
192 % 10 = 2
So 288087-83-2 is a valid CAS Registry Number.

Condensation of 2-hydroxyacetophenones with trichloroacetonitrile as a route to 2-trichloromethylchromones and 4-hydroxycoumarins

Sosnovskikh,Kutsenko,Ovsyannikov

, p. 478 - 481 (2007/10/03)

Condensation of 2-hydroxyacetophenones with trichloroacetonitrile in the presence of N-methylanilinomagnesium bromide affords hydroxyaryl β-amino-β-trichloromethylvinyl ketones, which are converted into 2-trichloromethylchromones upon treatment with concentrated HCl. The resulting compounds react with alcoholic solutions of NH3 or KOH to form 3-amino-1-(2-hydroxyaryl)-4,4,4-trichlorobut-2-en-1-ones and 4-hydroxycoumarins, respectively.
