Check Digit Verification of cas no

The CAS Registry Mumber 873949-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,9,4 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 873949-45:
(8*8)+(7*7)+(6*3)+(5*9)+(4*4)+(3*9)+(2*4)+(1*5)=232
232 % 10 = 2
So 873949-45-2 is a valid CAS Registry Number.

Fully stereocontrolled total syntheses of the prostacyclin analogues 16S-iloprost and 16S-3-oxa-iloprost by a common route, using alkenylcopper-azoalkene conjugate addition, asymmetric olefination, and allylic alkylation

Kramp, Guido J.,Kim, Mikhail,Gais, Hans-Joachim,Vermeeren, Cornelia

, p. 17910 - 17920 (2005)

In this article we describe fully stereocontrolled total syntheses of 16S-iloprost (16S-2), the most active component of the drugs Ilomedin and Ventavis, and of 16S-3-oxa-iloprost (16S-3), a close analogue of 16S-2 having the potential for a high oral act
