Check Digit Verification of cas no

The CAS Registry Mumber 135557-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135557-99:
(8*1)+(7*3)+(6*5)+(5*5)+(4*5)+(3*7)+(2*9)+(1*9)=152
152 % 10 = 2
So 135557-99-2 is a valid CAS Registry Number.

STEREOSPECIFIC REDUCTION OF DIASTEREOMERICALLY PURE MENTHYL PHOSPHINATES: A NEW ROUTE TO OPTICALLY ACTIVE PHOSPHINE OXIDES

Koide, Yasuhiro,Sakamoto, Atsushi,Imamoto, Tsuneo

, p. 3375 - 3376 (2007/10/02)

Diastereomerically pure menthyl phosphinates are stereospecifically reduced by lithium 4,4'-di-tert-butylbiphenylide.Subsequent treatment with alkyl halides affords phosphine oxides with high optical purity.

DETERMINATION OF THE ABSOLUTE CONFIGURATIONS OF 1,2-DIPHOSPHINYLETHENES POSSESSING TWO NONEQUIVALENT ASYMMETRIC PHOSPHORUS CENTRES. CRYSTAL STRUCTURE OF (R,S)-1-(tert-BUTYLPHENYLPHOSPHINYL)-2-(METHYL-PHENYLPHOSPHINYL)ETHANE.

Pietrusiewicz, K. Michal,Zablocka,Maria,Wieczorek, Wanda

, p. 183 - 190 (2007/10/02)

Using signle-crystal X-ray diffraction technique the R,S configuration has been assigned to a homochiral (-)-1-tert-butylphenylphosphinyl-2-methhylphenylphosphinylethane.This has allowed the assignment of absolute configuration also to its P1-epimer as we

OPTICALLY ACTIVE PHOSPHINE OXIDES. 4. A STRAIGHTFORWARD SYNTHESIS OF P-CHIRAL 1,2-DIPHOSPHINOYLETHANES.

Pietrusiewicz, K. Michal,Zablocka, Maria

, p. 1987 - 1990 (2007/10/02)

The title compounds possesing either one or two homochiral phosphorus centres are conveniently prepared via non-catalyzed addition of secondary phosphine oxides to an optically active vinyl phosphine oxide.
