Check Digit Verification of cas no

The CAS Registry Mumber 144358-24-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,3,5 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144358-24:
(8*1)+(7*4)+(6*4)+(5*3)+(4*5)+(3*8)+(2*2)+(1*4)=127
127 % 10 = 7
So 144358-24-7 is a valid CAS Registry Number.

Structurally simplified squalestatins: A convenient route to a 6,7-unsubstituted derivative

Lester,Gilbin,Inglis,Procopiou,Ross,Watson

, p. 4357 - 4360 (1993)

The squalestatin 1, has been converted into the 6,7-unsubstituted analogue, 3, via inversion of the alcohol at C7, selective removal of the α,β-unsaturated ester at C6 followed by a Corey-Hopkins deoxygenation of the generated 6R,7S-diol.

The Squalestatins: Novel Inhibitors of Squalene Synthase. Enzyme Inhibitory Activities and in Vivo Evaluation of C1-Modified Analogues

Procopiou, Panayiotis A.,Bailey, Esme J.,Bamford, Mark J.,Craven, Andy P.,Dymock, Brian W.,et al.

, p. 3274 - 3281 (2007/10/02)

Squalestatin analogues modified in the C1 side chain were prepared and evaluated for their ability to inhibit rat liver microsomal and Candida squalene synthase (SQS) in vitro.While maintaining the 4,6-dimethyloctenoate or 4,6-dimethyloctanoate ester grou

Chemoselective removal and replacement of the C-4' and C-6 acyl esters of zaragozic acid A

Burk,Berger,Bugianesi,Girotra,Parsons,Ponpipom

, p. 975 - 978 (2007/10/02)

An efficient chemical sequence is described for the modification of the C-4' and C-6 positions of zaragozic acid A. Key reactions include the specific conditions devised for selective removal of either the C-4' acetate or the C-6 acyl chain. The resultant
