717127-50-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 717127-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,7,1,2 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 717127-50:
(8*7)+(7*1)+(6*7)+(5*1)+(4*2)+(3*7)+(2*5)+(1*0)=149
149 % 10 = 9
So 717127-50-9 is a valid CAS Registry Number.

Azabicyclo[3.1.0]hexane-1-ols as frameworks for the asymmetric synthesis of biologically active compounds

Jida, Mouhamad,Guillot, Régis,Ollivier, Jean

, p. 8765 - 8767 (2008/03/18)

Azabicyclo[3.1.0]hexane-1-ols, easily obtained by Ti(IV)-mediated cyclopropanation of amino acid derivatives, constitute versatile, and unprecedented intermediates for the asymmetric synthesis of pharmacologically active products. Indeed, through selective rearrangement, these compounds undergo unusual ring cleavage to lead to pyrrolidinones. Fe(III)-promoted ring opening followed by basic dehydrohalogenation furnishes optically active dihydropyridinones, while Ce(IV)-promoted ring opening provides chiral tricyclopiperidinones via a radical process.
