143890-10-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143890-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,9 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143890-10:
(8*1)+(7*4)+(6*3)+(5*8)+(4*9)+(3*0)+(2*1)+(1*0)=132
132 % 10 = 2
So 143890-10-2 is a valid CAS Registry Number.

An Asymmetric Route to Enantiomerically Pure 1,2,3-Trisubstituted Cyclopropanes
Romo, Daniel,Meyers, A. I.
, p. 6265 - 6270 (2007/10/02)
Cycloadditions of various sulfur ylides to the chiral unsaturated lactams 1a, 1b led to cyclopropanated products containing a monosubstituted appendage.The stereochemical outcome is such that all the products are mainly (or exclusively) the kinetically co
