116660-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116660-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,6 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116660-68:
(8*1)+(7*1)+(6*6)+(5*6)+(4*6)+(3*0)+(2*6)+(1*8)=125
125 % 10 = 5
So 116660-68-5 is a valid CAS Registry Number.

Mamane, Victor,Gress, Tobias,Krause, Helga,Fuerstner, Alois
, p. 8654 - 8655 (2007/10/03)
Exposure of enynes containing a hydroxyl group at one of the propargylic positions to catalytic amounts of either PtCl2 or (PPh3)AuCl/AgSbF6 results in a selective rearrangement with formation of bicyclo[3.1.0]hexan-3-one
