740816-18-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 740816-18-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,8,1 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 740816-18:
(8*7)+(7*4)+(6*0)+(5*8)+(4*1)+(3*6)+(2*1)+(1*8)=156
156 % 10 = 6
So 740816-18-6 is a valid CAS Registry Number.

Enantioselective formation of quaternary stereocenters using the catalytic intramolecular Stetter reaction
Moore, Jennifer L.,Kerr, Mark S.,Rovis, Tomislav
, p. 11477 - 11482 (2006)
Asymmetric formation of quaternary stereocenters has been accomplished using the catalytic intramolecular Stetter reaction. A?variety of tethered aldehydes and Michael acceptors are cyclized in excellent yields and enantioselectivities.
