138710-25-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138710-25-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,1 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138710-25:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*0)+(2*2)+(1*5)=125
125 % 10 = 5
So 138710-25-5 is a valid CAS Registry Number.

Electronic effects on π-facial stereoselectivity in electrophilic additions to allylic bonds: Stereoselective epoxidation of allylic fluorides

Fujita, Makoto,Ishizuka, Hidemi,Ogura, Katsuyuki

, p. 6355 - 6358 (2007/10/02)

The electronic stabilization of the transition state in electrophilic additions to allylic bonds is discussed through m-CPBA oxidation of allylic fluorides; the stereoselectivity is interpreted by a transition-state model where the most electronegative atom (fluorine) is oriented at the inside position as supported by theoretical examinations.
