119138-74-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 119138-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,3 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119138-74:
(8*1)+(7*1)+(6*9)+(5*1)+(4*3)+(3*8)+(2*7)+(1*4)=128
128 % 10 = 8
So 119138-74-8 is a valid CAS Registry Number.

Selective Heteronuclear NOE Enhancements in Benzoheterocycles. Effect of Ring Size on Indirect Three-Spin Effects

Redondo, Jordi,Sanchez-Ferrando, Francisco,Valls, Montserrat,Virgili, Albert

, p. 511 - 517 (1988)

The 80 MHz 1H NMR and 20 MHz 13C NMR spectra of five 4-methylcoumarins, six 4-methyl-2(1H)-quinolones and nine 3-methylbenzofurans, including six new compounds, were fully assigned.Homonuclear 1H NOEs and selective heteronuclear 13C NOEs were measured after low-power pre-saturation of the methyl protons.Indirect, negative heteronuclear NOE enhancements were found in suitable three-spin systems of the 13C-1H- type, and their magnitude was found to be dependent on ring size.The first examples of indirect, heteronuclear NOE enhancements on non-protonated carbons are described.KEY WORDS Heteronuclear NOE Selective heteronuclear 13C NOE Indirect negative NOE 13C-1H- three-spin effects Coumarins 2(1H)-Quinolones Benzofurans.
