Check Digit Verification of cas no

The CAS Registry Mumber 140239-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,2,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140239-19:
(8*1)+(7*4)+(6*0)+(5*2)+(4*3)+(3*9)+(2*1)+(1*9)=96
96 % 10 = 6
So 140239-19-6 is a valid CAS Registry Number.

Efficient procedure to 4-carbethoxy-3-trifluoro methylcyclohex-2-enone and 4-alkylated derivatives

Begue,Bonnet-Delpon,Dogbeavou

, p. 573 - 579 (1992)

The 4-carbethoxy-3-trifluoromethylcyclohex-2-enone 1a was prepared in one-pot procedure in 90% yield, from ethyl trifluoroacetoacetate (ETFAAE) and methylvinyl ketone. This reaction has been extended to alkylated ethyl trifluoroacetoacetate.
