Check Digit Verification of cas no
The CAS Registry Mumber 10556-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,5,5 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10556-91:
(7*1)+(6*0)+(5*5)+(4*5)+(3*6)+(2*9)+(1*1)=89
89 % 10 = 9
So 10556-91-9 is a valid CAS Registry Number.

ALKYLATION DU TRIFLUOROACETYLACETATE D'ETHYLE METHODE GENERALE D'ACCES AUX TRIFLUOROMETHYLCETONES. 2eme PARTIE: ALKYLATIONS INDIRECTS DU TFAAE

A versatile method of alkylation of ethyltrifluoroacetylacetate (ETFAA) allowed selective C-alkylation of ETFAA, whatever the structure of alkyl halide was, providing that the carbonyl function was masked into a dioxolan 3 or a N,N-dimethyl hydrazone 5.These last derivatives were easily alkylated and their specific deprotection led to various C-alkylated ETFAA which in turn allowed, by a simple decarbethoxylation, the preparation of the corresponding trifluoromethyl ketones in good yields.
