251556-92-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 251556-92-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,5,5 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 251556-92:
(8*2)+(7*5)+(6*1)+(5*5)+(4*5)+(3*6)+(2*9)+(1*2)=140
140 % 10 = 0
So 251556-92-0 is a valid CAS Registry Number.

Stereocontrolled preparation of the C1-C14 polyene fragment of benzenic ansamycin antibiotics ansatrienin A and B

Sch?ning, Kai-Uwe,Wittenberg, Rüdiger,Kirschning, Andreas

, p. 1624 - 1626 (1999)

A practical synthesis of the C1-C14 polyene unit 5 in ansatrienin A (mycotrien l), 1a, and other ansamycin antibiotics is described which involves elaboration of the chiral unsaturated aldehyde 6 and phosphonate 7, followed by coupling of the building blocks by Horner-Emmons-olefination and Duthaler's aldolation. The synthesis of 6 successfully applies two consecutive Evans-aldol reactions for constructing the carbon backbone.
