Check Digit Verification of cas no

The CAS Registry Mumber 20449-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,4 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20449-21:
(7*2)+(6*0)+(5*4)+(4*4)+(3*9)+(2*2)+(1*1)=82
82 % 10 = 2
So 20449-21-2 is a valid CAS Registry Number.

Formation of acetals under rhodium-catalyzed hydroformylation conditions in alcohols

Diebolt, Olivier,Cruzeuil, Clement,Mueller, Christian,Vogt, Dieter

supporting information; experimental part, p. 670 - 677 (2012/04/23)

Hydroformylation of terminal alkenes in alcohol solvents leads to the selective formation of the corresponding acetals. The Xantphos ligand gave the best results as well as acetal selectivities higher than 99% and linear/branched ratios of up to 52 were obtained. The scope of the reaction was studied. Acetals were found to be unreactive under hydroaminomethylation conditions. Copyright
