Check Digit Verification of cas no

The CAS Registry Mumber 118335-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,3 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118335-07:
(8*1)+(7*1)+(6*8)+(5*3)+(4*3)+(3*5)+(2*0)+(1*7)=112
112 % 10 = 2
So 118335-07-2 is a valid CAS Registry Number.

Synthesis and First X-Ray Structure Analysis of a Stabilized Chiral Chlorobismuthine: Fixation of Molecular Geometry Induced by the Intramolecular Coordination of a Sulfonyl Group

Suzuki, Hitomi,Murafuji, Toshihiro,Azuma, Nagao

, p. 1169 - 1176 (2007/10/02)

A sulfonyl-stabilized chiral chlorobismuthine 1a was synthesized by the selective fluorodearylation of compound 3a with boron trifluoride-diethyl ether, followed by halogen exchange of the resulting fluorobismuthine 4a with brine.The (1)H NMR spectrum of compound 1a showed an unusually large downfield shift of a proton signal (δ 9.16), and X-ray structure analysis revealed that this unique shift was due to the anisotropic deshielding of the proton adjacent to the bismuth atom by the chlorine atom in close proximity.The bismuth centre of compound 1a was found to adopt a distorted pseudotrigonal bipyramidal geometry, probably through the formation of a hypervalent 3-centre 4-electron bond with the oxygen and chlorine atoms at apical positions.This is in marked contrast to the bismuthine 3a which has a pyramidal configuration characteristic of trivalent organobismuth compounds.A quite short Bi-O distance of compound 1a, compared with that of the bismuthine 3a, indicates that the introduction of an electronegative chlorine atom onto the bismuth atom enhances the Lewis acidity of the metal centre, leading to the pronounced intramolecular Bi-O interaction.
