139684-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139684-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,8 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139684-98:
(8*1)+(7*3)+(6*9)+(5*6)+(4*8)+(3*4)+(2*9)+(1*8)=183
183 % 10 = 3
So 139684-98-3 is a valid CAS Registry Number.

A proline-catalyzed asymmetric Robinson annulation reaction

Bui,Barbas III

, p. 6951 - 6954 (2000)

A single-step enantioselective synthesis of the Wieland-Miescher ketone (5) is presented. We show that L-proline as well as a number of other chiral amines can act as catalysts of both steps of the Robinson annulation reaction. Other chiral amines are identified as catalysts of Michael and aldol addition reactions. (C) 2000 Elsevier Science Ltd.
