127944-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127944-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127944-40:
(8*1)+(7*2)+(6*7)+(5*9)+(4*4)+(3*4)+(2*4)+(1*0)=145
145 % 10 = 5
So 127944-40-5 is a valid CAS Registry Number.

INFLUENCE OF OLEFIN COORDINATION ON CYCLOPROPANATION SELECTIVITY
Doyle, Michael P.,Wang, Linda C.,Loh, Kuo-Liang
, p. 4087 - 4090 (2007/10/02)
Catalyst-dependent differences in regioselectivity for cyclopropanation result from the degree of charge development in the transition state rather than from intramolecular collapse of a coordinated olefin.
