128854-60-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128854-60-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,5 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128854-60:
(8*1)+(7*2)+(6*8)+(5*8)+(4*5)+(3*4)+(2*6)+(1*0)=154
154 % 10 = 4
So 128854-60-4 is a valid CAS Registry Number.

Asymmetric Radical Reaction in the Coordination Sphere. 2. Asymmetric Addition of Alkane- and Arenesulfonyl Chlorides to Olefins Catalyzed by a Ruthenium(II)-Phosphine Complex with Chiral Ligands

Kameyama, Masayuki,Kamigata, Nobumasa,Kobayashi, Michio

, p. 3312 - 3316 (1987)

The addition of arenesulfonyl chlorides to styrene in the presence of a catalytic amount of a ruthenium(II) complex with chiral phosphine ligands, Ru2Cl43 or Ru2Cl43, proceeds under mild conditions to give optically active 1:1 adducts,

Enantiomerically Pure Acetals in Organic Synthesis. 1. Chromatographic Separability of Furanoside and Pyranoside Acetals Derived from α-Hydroxy Esters

Mash, Eugene A.,Arterburn, Jeffrey B.,Fryling, James A.,Mitchell, Susan H.

, p. 1088 - 1093 (2007/10/02)

A general chromatographic separation of diastereomeric furanoside and pyranoside acetals derived from α-hydroxy esters is described.Application of this separation methodology is made to rapid syntheses of the diastereomers of (S)-methyl lactyl 4-deoxy-β-erythro-pentopyranoside.
