Check Digit Verification of cas no

The CAS Registry Mumber 586390-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,6,3,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 586390-99:
(8*5)+(7*8)+(6*6)+(5*3)+(4*9)+(3*0)+(2*9)+(1*9)=210
210 % 10 = 0
So 586390-99-0 is a valid CAS Registry Number.

Stereospecific synthesis of 2,2,3-trisubstituted tetrahydroquinolines: Application to the total syntheses of benzastatin E and natural virantmycin

Ori, Mayuko,Toda, Narihiro,Takami, Kazuko,Tago, Keiko,Kogen, Hiroshi

, p. 2075 - 2104 (2007/10/03)

An efficient methodology for the synthesis of 2,2,3-trisubstituted tetrahydroquinolines has been developed, which involves the triphenylphosphine- CCl4-mediated stereospecific rearrangement of α,α- disubstituted indoline-2-methanols 15 to 2,2,3-trisubstituted tetrahydroquinolines 26. The rearrangement precursors 15 are readily prepared by the diastereoselective Grignard addition to 2-acylindolines 13. The total syntheses of (+)-benzastatin E (1) and natural virantmycin (2a) were accomplished utilizing this methodology. This rearrangement reaction might afford some chemical precedent for the biogenetic pathway of the benzastatin family.
