Check Digit Verification of cas no

The CAS Registry Mumber 597557-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,7,5,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 597557-40:
(8*5)+(7*9)+(6*7)+(5*5)+(4*5)+(3*7)+(2*4)+(1*0)=219
219 % 10 = 9
So 597557-40-9 is a valid CAS Registry Number.

Asymmetric synthesis of the highly potent anti-metastatic prostacyclin analogue cicaprost and its isomer isocicaprost

Lerm, Marco,Gais, Hans-Joachim,Cheng, Kejun,Vermeeren, Cornelia

, p. 9653 - 9667 (2007/10/03)

An asymmetric synthesis of the anti-metastatic prostacyclin analogue cicaprost and a formal one of its isomer isocicaprost by a new route are described. A key step of these syntheses is the coupling of a chiral bicyclic C6-C14 ethynyl building block with
