Check Digit Verification of cas no

The CAS Registry Mumber 945494-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,4,9 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 945494-69:
(8*9)+(7*4)+(6*5)+(5*4)+(4*9)+(3*4)+(2*6)+(1*9)=219
219 % 10 = 9
So 945494-69-9 is a valid CAS Registry Number.

Asymmetric hydroformylation of vinyl acetate: Application in the synthesis of optically active isoxazolines and imidazoles

Thomas,Axtell, Alex T.,Klosin, Jerzy,Wei, Peng,Rand, Cynthia L.,Clark, Thomas P.,Landis, Clark R.,Abboud, Khalil A.

, p. 2665 - 2668 (2008/02/09)

Equation Presented (R)- and (S)-2-(Acetyloxy)-propanal were prepared [93.8% ee, 102 b/l for (R), 96.9% ee, 149 b/l for (S)] via asymmetric hydroformylation of vinyl acetate on a 150-180 g scale and were used as the starting materials in the synthesis of chiral isoxazoline and imidazole derivatives which proceeded without racemization of the chiral center.
