70181-25-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70181-25-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,1,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70181-25:
(7*7)+(6*0)+(5*1)+(4*8)+(3*1)+(2*2)+(1*5)=98
98 % 10 = 8
So 70181-25-8 is a valid CAS Registry Number.

Regioselective Coupling Reaction of Allylic Barium Reagents with Epoxides
Yasue, Katsutaka,Yanagisawa, Akira,Yamamoto, Hisashi
, p. 492 - 498 (2007/10/03)
The regioselective coupling reaction of epoxides with allylic barium reagents was achieved. All reactions resulted in high yields with remarkable α-selectivities. 2-Propynylbarium reagent afforded exclusively the corresponding acetylenic alcohol.
