Check Digit Verification of cas no

The CAS Registry Mumber 1129399-39-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,9,3,9 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1129399-39:
(9*1)+(8*1)+(7*2)+(6*9)+(5*3)+(4*9)+(3*9)+(2*3)+(1*9)=178
178 % 10 = 8
So 1129399-39-8 is a valid CAS Registry Number.

Asymmetric desymmetrization of the diallyl acetals of alkynals by the enantioselective Pauson-Khand-type reaction catalysts

supporting information; experimental part, p. 2695 - 2700 (2009/10/14)

Asymmetric desymmetrization of the di-allyl acetals of alkynal (1) by an enantioselective Pauson-Khand-type reaction catalyst was studied. The corresponding 5-oxabicyclo[3.3.0]octenones (2) were obtained as a mixture of diastereomers (2a and 2b), which were hydrolyzed to afford a single enantiomer (3), in high yields (up to 88%) as well as excellent enantioselectivities (up to 97%).
