638203-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 638203-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,8,2,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 638203-45:
(8*6)+(7*3)+(6*8)+(5*2)+(4*0)+(3*3)+(2*4)+(1*5)=149
149 % 10 = 9
So 638203-45-9 is a valid CAS Registry Number.

Advances in analysis and synthesis of myo-inositol-derivatives through resolution by crystallisation

Wewers, Wolfgang,Gillandt, Hartmut,Traub, Henner Schmidt

, p. 1723 - 1728 (2007/10/03)

A simple method for the preparation of both enantiomers of tetra-O-benzyl-myo-inositol is presented. This method is based on the resolution of stereoisomers by crystallisation. Starting with the known synthesis of four diastereomers using d-camphor dimeth

L-chiro-inositol derivatives from myo-inositol. Building blocks for inositolphosphoglycans

Cid, M. Belén,Alfonso, Francisco,Martín-Lomas, Manuel

, p. 1370 - 1372 (2007/10/03)

A straightforward synthesis of L-chiro-inositol, deoxy L-chiro-inositol derivatives and L-chiro-inositol building blocks for the preparation of inositolphosphoglycans, is reported from myoinositol. Glycosylation with 2-azido-3,4,6-tri-O-benzyl-2-deoxy-D-g

Concise syntheses of L-α-phosphatidyl-D-myo-inositol 3-phosphate (3- PIP), 5-phosphate (5-PIP), and 3,5-bisphosphate (3,5-PIP2)

Falck,Krishna, U. Murali,Katipally, Kishta Reddy,Capdevila, Jorge H.,Ulug, Emin T.

, p. 4271 - 4275 (2007/10/03)

Highly efficient, asymmetric total syntheses of the title phospholipids as well as short chain and crosslinkable aminoether analogs were achieved in five to seven steps from a readily available myo-inositol derivative. (C) 2000 Elsevier Science Ltd.
