Check Digit Verification of cas no
The CAS Registry Mumber 35238-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,2,3 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35238-97:
(7*3)+(6*5)+(5*2)+(4*3)+(3*8)+(2*9)+(1*7)=122
122 % 10 = 2
So 35238-97-2 is a valid CAS Registry Number.

Chiral phosphino(sulfinylmethyl)triarylphosphonium ylide ligands: Rhodium complexes and catalytic properties
Zurawinski, Remigiusz,Donnadieu, Bruno,Mikolajczyk, Marian,Chauvin, Remi
, p. 4810 - 4817 (2008/10/09)
A novel phosphine-phosphonium ylide ligand bearing a chiral sulfinyl moiety was prepared by reaction of (o-diphenylphosphinophenyl)diphenylphosphonium methylide with (S)-menthyl p-tolylsulfinate. Reaction of this ylide with [Rh(cod)2][PF6] gave stable cationic disymmetrically P,C-chelated rhodium complexes with an asymmetric ylidic carbon atom anchored to the metal center. The configuration of this carbon is controlled by the S-configuration of the adjacent sulfinyl group. The stereoselectivity of the complexation is reversed from 9:1 at 20 °C to 1:9 at -45°C. An X-ray diffraction analysis of the thermodynamic complex shows that the stereoselectivity is not directed by chelation of the SO group which lies at a nonbonding distance from the rhodium center. In the presence of triethylamine, epimerization occurs via a putative neutral P,C-chelated complex bearing an yldiide ligand. In the presence of HPF6 and PPh3, cleavage of the ylidic carbon-rhodium bond takes place simultaneously with displacement of the phosphino-phosphonium ligand by PPh3. The phosphine end of the ligand is intended to preserve at least one phosphine-rhodium bond, which is a common feature of all the rhodium catalysts derived from the Wilkinson complex. Indeed, we found that the phosphino-phosphonium ylide complexes are active-though poorly enantioselective-as catalysts for hydrogenation of (Z)-α-acetamidocinnamic acid and hydrosilylation of acetophenone.
