Check Digit Verification of cas no

The CAS Registry Mumber 471270-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,1,2,7 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 471270-17:
(8*4)+(7*7)+(6*1)+(5*2)+(4*7)+(3*0)+(2*1)+(1*7)=134
134 % 10 = 4
So 471270-17-4 is a valid CAS Registry Number.

Studies towards the total synthesis of solanoeclepin A: Synthesis and potato cyst nematode hatching activity of analogues containing the tetracyclic left-hand substructure

Benningshof, Jorg C. J.,IJsselstijn, Maarten,Wallner, Sabine R.,Koster, Anne L.,Blaauw, Richard H.,Van Ginkel, Angeline E.,Briere, Jean-Francois,Van Maarseveen, Jan H.,Rutjes, Floris P. J. T.,Hiemstra, Henk

In our studies towards the total synthesis of solanoeclepin A, a natural hatching agent of potato cyst nematodes, three analogues containing the tetracyclic left-handed substructure have been synthesised. First, the synthesis of the parent tetracycle 2 in

Enantioselectve synthesis of the tetracyclic left-hand substructure of solanoeclepin A

Benningshof,Blaauw,Van Ginkel,Rutjes,Fraanje,Goubitz,Schenk,Hiemstra

, p. 1465 - 1466 (2007/10/03)

The synthesis of the enantiopure left-hand substructure of solanoeclepin A is described. Key steps include a chromium-mediated coupling of an oxabicyclic aldehyde with a β-ketoester-derived enol triflate to give a lactone, and a ring-closing metathesis reaction to form the seven-membered ring.
