Check Digit Verification of cas no

The CAS Registry Mumber 102997-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,9 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 102997-58:
(8*1)+(7*0)+(6*2)+(5*9)+(4*9)+(3*7)+(2*5)+(1*8)=140
140 % 10 = 0
So 102997-58-0 is a valid CAS Registry Number.

Synthesis of cyclitols via ring-closing metathesis

Kornienko, Alexander,D'Alarcao, Marc

, p. 827 - 829 (1999)

A convenient synthesis of enantiomerically pure and differentially protected L-chiro- and myo-inositols as well as conduritols B and F from 2,3,4-tri-O-benzyl-D-xylopyranose via ring-closing metathesis is reported. The facile synthesis of conduritol B con

Synthesis of cyclophellitol utilizing a palladium chloride mediated-ferrier-II rearrangement

Takahashi, Hideyo,Ikegami, Shiro

, p. 901 - 911 (2007/10/03)

Cyclophellitol and its C3-epimer have been synthesized from 5-enoglucopyranoside and 5-enomannopyranoside, respectively. The carbocyclic skeleton was constructed through a Ferrier-II reaction meditated by PdCl 2.

An effective strategy for the synthesis of 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-chiro- and -D-myo-inositol 1-phosphate related to putative insulin mimetics

Jaramillo,Chiara,Martin-Lomas

, p. 3135 - 3141 (2007/10/02)

Two glycosylinositol phosphates related to putative insulin mimetics, 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-chiro-inositol 1-phosphate (1) and 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol 1-phosphate (2), have been synthesized from selectively protected and enantiomerically pure D-chiro- and myo-inositol derivatives. The D-chiro-inositol unit was prepared in a multigram scale from D-glucose using the Ferrier's carbocyclization route, and it was transformed into the corresponding myo epimer by an oxidation-reduction sequence. The trichloroacetimidate method was applied efficiently for the key glycosylation of the inositol derivatives.
