Check Digit Verification of cas no

The CAS Registry Mumber 688049-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,0,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 688049-03:
(8*6)+(7*8)+(6*8)+(5*0)+(4*4)+(3*9)+(2*0)+(1*3)=198
198 % 10 = 8
So 688049-03-8 is a valid CAS Registry Number.

Asymmetric aldol reactions from titanium enolates of α-seleno ketones and esters

Tiecco, Marcello,Testaferri, Lorenzo,Marini, Francesca,Sternativo, Silvia,Santi, Claudio,Bagnoli, Luana,Temperini, Andrea

, p. 783 - 791 (2004)

Asymmetric aldol condensations using titanium enolates of (R)-camphorselenoacetone and of methyl (R)-camphorselenoacetate are reported. The reactions with aromatic, α,β-unsaturated or aliphatic aldehydes proceed with good chemical yields giving a mixture of the syn and anti aldols. These diastereoisomers were easily separated by column chromatography. The two syn diastereoisomers were obtained in enantiomerically pure form.
