851645-72-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 851645-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,6,4 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 851645-72:
(8*8)+(7*5)+(6*1)+(5*6)+(4*4)+(3*5)+(2*7)+(1*2)=182
182 % 10 = 2
So 851645-72-2 is a valid CAS Registry Number.

supporting information; experimental part, p. 6467 - 6470 (2012/07/27)

Transfer news: A synthetic approach to chiral β-CF3- substituted saturated carbonyl compounds has been developed in which ruthenium complexes efficiently catalyze the redox isomerization of CF3-bearing allylic alcohols by an intramol

Regioselective synthesis of β-fluoro-α,β-unsaturated ketones by the reaction of β-diketones with DFMBA

Sano, Keisuke,Fukuhara, Tsuyoshi,Hara, Shoji

experimental part, p. 708 - 713 (2010/04/05)

The deoxyfluorination reaction of β-diketones with N,N-diethyl-α,α-difluoro-m-methylbenzylamine (DFMBA) gave β-fluoro-α,β-unsaturated ketones in good yields. The reaction proceeded regioselectively, and only one regioisomer was obtained from the unsymmetr
