Check Digit Verification of cas no

The CAS Registry Mumber 146844-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146844-74:
(8*1)+(7*4)+(6*6)+(5*8)+(4*4)+(3*4)+(2*7)+(1*4)=158
158 % 10 = 8
So 146844-74-8 is a valid CAS Registry Number.

Untersuchungen an Arylbleitriacetaten. Roentgenstrukturanalyse von 2-Methylphenyl- und 2-Chlorophenylbleitriacetat

Huber, F.,Preut, H.,Scholz, D.,Schuermann, M.

, p. 227 - 239 (2007/10/02)

The crystal structures of 2-XC6H4Pb(OAc)3 (X = CH3, Cl; OAc = OOCCH3) have been determined by X-ray diffraction.Both compounds are isostructural and crystallize as triclinic, space group P.They consist of monomers, the seven-coordinated central atom being in a distorted pentagonal-bipyramidal environment with five O atoms of the three unsymmetrically chelating carboxylate groups in equatorial positions, and one O and one C(aryl) atom in axial positions.IR, 1H, 13C and 207Pb NMR spectroscopic data of these and other monoaryllead triacetates are reported, and similar structures with seven-coordinated lead are inferred.Weak coordination of Y to Pb is discussed to exist possibly in 2-YC6H4Pb(OAc)3 (Y = F, Cl, OCH3).
