Check Digit Verification of cas no

The CAS Registry Mumber 130159-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,5 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130159-25:
(8*1)+(7*3)+(6*0)+(5*1)+(4*5)+(3*9)+(2*2)+(1*5)=90
90 % 10 = 0
So 130159-25-0 is a valid CAS Registry Number.

Ytterbium triflate-promoted tandem one-pot oxidation-cannizzaro reaction of aryl methyl ketones

Curini, Massimo,Epifano, Francesco,Genovese, Salvatore,Marcotullio, M. Carla,Rosati, Ornelio

, p. 1331 - 1333 (2005)

(Chemical Equation Presented) Ytterbium triflate was shown to be an effective catalyst in promoting the synthesis of either isopropyl esters or free α-hydroxy-arylacetic acids from substituted aromatic glyoxals and aryl methyl ketones, respectively. The reaction to provide acids starting from differently substituted ketones was carried out by an environmentally friendly method using an aqueous medium as a solvent and giving the adducts in 78-99% yield without any further purification after the usual workup.

Catalysis by Cobalt Schiff's Base Complexes in Highly Selective Conversion of Arylglyoxals to α-Aryl-α-hydroxyacetic Esters

Maruyama, K.,Murakami, Y.,Yoda, K.,Mashino, T.,Nishinaga, A.

, p. 1617 - 1618 (2007/10/02)

Cobalt Schiff's base complexes catalyse highly selective conversion of arylglyoxals to α-aryl-α-hydroxyacetic esters in alcohols; Lewis acidity of CoIII species may be responsible to the catalysis.
