Check Digit Verification of cas no

The CAS Registry Mumber 303727-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,7,2 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 303727-85:
(8*3)+(7*0)+(6*3)+(5*7)+(4*2)+(3*7)+(2*8)+(1*5)=127
127 % 10 = 7
So 303727-85-7 is a valid CAS Registry Number.

Gram-scale synthesis of (+)-discodermolide.

Smith 3rd.,Kaufman,Beauchamp,LaMarche,Arimoto

, p. 1823 - 1826 (1999)

[formula: see text] A triply convergent, highly efficient second-generation synthesis of the potent antimitotic agent (+)-discodermolide (1) has been achieved on a 1-g scale.

Evolution of a gram-scale synthesis of (+)-discodermolide

Smith III, Amos B.,Beauchamp, Thomas J.,LaMarche, Matthew J.,Kaufman, Michael D.,Qiu, Yuping,Arimoto, Hirokazu,Jones, David R.,Kobayashi, Kaoru

, p. 8654 - 8664 (2007/10/03)

An efficient, highly convergent, stereocontrolled total synthesis of the potent antimitotic agent (+)-discodermolide (1) has been achieved on gram scale. Key elements of the successful strategy include (1) elaboration of three advanced fragments from a common precursor (CP) which embodies the repeating stereochemical triad of the discodermolide backbone, (2) σr-bond installation of the Z trisubstituted olefin, exploiting a modified Negishi cross-coupling reaction, (3) synthesis of a late-stage phosphonium salt utilizing high pressure, and (4) Wittig installation of the Z disubstituted olefin and the terminal (Z)-diene.
