76143-12-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76143-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 76143-12:
(7*7)+(6*6)+(5*1)+(4*4)+(3*3)+(2*1)+(1*2)=119
119 % 10 = 9
So 76143-12-9 is a valid CAS Registry Number.

Step-economical synthesis of tetrahydroquinolines by asymmetric relay catalytic Friedlaender condensation/transfer hydrogenation

Ren, Lei,Lei, Tao,Ye, Jia-Xi,Gong, Liu-Zhu

supporting information; experimental part, p. 771 - 774 (2012/02/05)

Two steps in one reaction: The title relay reaction relies on a combination of an achiral Lewis acid and a chiral Bronsted acid (B-H in the scheme). This one-pot method provides access to tetrahydroquinoline derivatives with multiple continuous stereogeni
