Check Digit Verification of cas no

The CAS Registry Mumber 123355-00-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,5 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123355-00:
(8*1)+(7*2)+(6*3)+(5*3)+(4*5)+(3*5)+(2*0)+(1*0)=90
90 % 10 = 0
So 123355-00-0 is a valid CAS Registry Number.

Synthesis of both enantiomers of conduritol C tetraacetate and of meso-conduritol D tetraacetate by oxidation of benzoquinone bis(ethylene acetal)

Lang, Martin,Ziegler, Thomas

, p. 768 - 776 (2008/02/07)

Epoxidation of p-benzoquinone bis(ethylene acetal) (1) with m-chloroperbenzoic acid or hydrogen peroxide/benzonitrile afforded corresponding monoepoxide 2, which was converted into p-benzoquinone mono(ethylene acetal) monoepoxide 5 with perchloric acid. D

Synthesis of haloconduritols from an endo-cycloadduct of furan and vinylene carbonate

Baran, Arif,Kazaz, Cavit,Se?en, Hasan,Sütbeyaz, Ya?ar

, p. 3643 - 3648 (2007/10/03)

A method for preparing haloconduritols having a conduritol-A construction is described. A mixture of endo- and exo-cycloadduct derivatives prepared from the Diels-Alder reaction of furan and vinylene carbonate was converted into diacetate derivatives by hydrolysis (K2CO3/MeOH) followed by acetylation (Ac2O/pyridine). Boron trihalide (BBr3 or BCl3)-assisted ring-opening of the endo-diacetate in CH2Cl2 at -78°C gave (1α,2α,3β,6β)-6-halogeno-4-cyclohexene-1,2,3-triol 1,2-diacetate from which the corresponding triacetate was prepared by acetylation (AcCl). trans-Esterification of the triacetate (MeOH/HCl) afforded (1α,2α,3β,6β)-6-halogeno-4-cyclohexene-1,2,3-triol (X=Br or Cl). BF3-Assisted ring-opening of the endo-diacetate in CH2Cl2 gave (1α,2α,3β,6β)-6-chloro-4-cyclohexene-1,2,3-triol 1,2-diacetate by means of halogen exchange.

Carbohydrate carbocyclization by a novel zinc-mediated domino reaction and ring-closing olefin metathesis

Hyldtoft, Lene,Madsen, Robert

, p. 8444 - 8452 (2007/10/03)

A general method for carbocyclization of carbohydrates is described using two consecutive organometallic transformations: a novel zinc-mediated domino reaction to give functionalized dienes followed by ring-closing olefin metathesis. In the first reaction
