Check Digit Verification of cas no

The CAS Registry Mumber 205238-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,2,3 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 205238-71:
(8*2)+(7*0)+(6*5)+(5*2)+(4*3)+(3*8)+(2*7)+(1*1)=107
107 % 10 = 7
So 205238-71-7 is a valid CAS Registry Number.

Asymmetric hydroformylation of olefins in highly crosslinked polymer matrixes

Nozaki, Kyoko,Shibahara, Fumitoshi,Itoi, Yohei,Shirakawa, Eiji,Ohta, Tetsuo,Takaya, Hidemasa,Hiyama, Tamejiro

, p. 1911 - 1918 (2007/10/03)

When polymer-immobilized chiral phosphine-phosphite-Rh(I) complexes were used, the asymmetric hydroformylation of styrene gave 2- and 3- phenylpropanals with a substrate/catalyst ratio of 2000, iso/normal ratios of 84/16 to 89/11, and 89% R enantiomeric excess of 2-phenylpropanal; these results were at the highest level in catalytic activity, regio-, and enantioselectivities. Recovery-reuse of the catalyst was examined. Asymmetric hydroformylation of vinyl acetate, (Z)-2-butene, and 3,3,3-trifluoropropene was also successfully performed with the polymer-supported catalysts.
