180890-43-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180890-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,8,9 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 180890-43:
(8*1)+(7*8)+(6*0)+(5*8)+(4*9)+(3*0)+(2*4)+(1*3)=151
151 % 10 = 1
So 180890-43-1 is a valid CAS Registry Number.

Chemo-selective oxidation of hydroxybenzyl alcohols with IBX in the presence of hemicucurbit[6]uril

Cong, Hang,Yamato, Takehiko,Tao, Zhu

, p. 3778 - 3783 (2013)

The chemo-selective oxidation of bifunctional substrates via a supramolecular strategy has been achieved. IBX (o-iodoxybenzoic acid) oxidations of hydroxybenzyl alcohols produce the corresponding aldehyde and o-quinones, while the presence of HemiQ[6] can restrain the IBX oxidation of phenolic hydroxyl groups to afford the aldehyde product. The conversion and reaction rate are greatly affected by the structures of substrates, and the stereo effect and electronic effect play very important roles in the selective oxidation system. Various spectroscopies, including 1H NMR (proton nuclear magnetic resonance), IR (infrared), and UV-vis (ultra violet-visible) have been employed to confirm the host-guest interaction of HemiQ[6] with hydroxybenzyl alcohols.
