278602-14-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 278602-14-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,8,6,0 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 278602-14:
(8*2)+(7*7)+(6*8)+(5*6)+(4*0)+(3*2)+(2*1)+(1*4)=155
155 % 10 = 5
So 278602-14-5 is a valid CAS Registry Number.

NMR spectroscopic data of some 1-alkoxy-2,2-di(carbonyl, carboxyl, cyano)-substituted ethylenes

Hametner, Christian,Cernuchova, Petra,Milata, Viktor,Vo-Thanh, Giang,Loupy, Andre

, p. 171 - 173 (2007/10/03)

The 1H-13C NMR shifts as well as 1H and 13C coupling constants of 14 alkoxymethylene malonic acid and acetoacetic acid derivatives and two alkoxymethylene acetylacetones are reported. The 17O NMR spectra have been recorded for six of them. The long-range coupling 3J(H-C=C-CR) has been used for determining the stereochemistry of the double bond. Copyright
