665053-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 665053-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,5,0,5 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 665053-54:
(8*6)+(7*6)+(6*5)+(5*0)+(4*5)+(3*3)+(2*5)+(1*4)=163
163 % 10 = 3
So 665053-54-3 is a valid CAS Registry Number.

Stereoselective Intramolecular Nicholas Reaction Using Epoxides as Nucleophiles
Crisostomo, Fernando R. P.,Martin, Tomas,Martin, Victor S.
, p. 565 - 568 (2007/10/03)
(Matrix presented) The intramolecular nucleophilic attack of the epoxides on the exo-Co2(CO)6-propargylic cations provided cyclic ethers in good yields. The use of substrates with stereochemically defined oxiranes provided polysubsti
