128442-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128442-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,4 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128442-41:
(8*1)+(7*2)+(6*8)+(5*4)+(4*4)+(3*2)+(2*4)+(1*1)=121
121 % 10 = 1
So 128442-41-1 is a valid CAS Registry Number.

Resolution of synthetically useful myo-inositol derivatives using the chiral auxiliary O-acetylmandelic acid

Sureshan, Kana M.,Kiyosawa, Yoko,Han, Fushe,Hyodo, Sayuri,Uno, Yuhki,Watanabe, Yutaka

, p. 231 - 241 (2007/10/03)

Efficient methods for the resolution of various myo-inositol derivatives have been developed using O-acetylmandelic acid (OAM) as the chiral auxiliary. Various methods of introduction of the chiral auxiliary have been compared. DCC mediated coupling betwe

A Chiral Synthesis of D-myo-Inositol 1-Phosphate Starting from L-Quebrachitol

Akiyama, Takahiko,Takechi, Naoto,Ozaki, Shoichiro,Shiota, Kenji

, p. 366 - 372 (2007/10/02)

A naturally occurring optically active cyclitol, L-quebrachitol (1L-2-O-methyl-chiro-inositol), was stereoselectively transformed into myo-inositol derivatives via an oxidation-reduction process.The methyl ether was cleaved chemoselectively with AlCl3NaI

SYNTHESIS OF SOME BENZYL AND METHYL ETHERS OF myo-INOSITOL

Garegg, Per J.,Lindberg, Bengt,Kvarnstroem, Ingemar,Svensson, Stefan C. T.

, p. 205 - 216 (2007/10/02)

The 1D and 1L forms of 1,2,4,5,6- and 1,2,3,4,5-penta-O-methyl-myo-inositol have been prepared from the corresponding chiral mono-O-benzyl derivatives.Convenient preparations are also described of achiral derivatives of 1-, 2-, 4-, and 5-O-benzyl-myo-inos
