869304-98-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 869304-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,3,0 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 869304-98:
(8*8)+(7*6)+(6*9)+(5*3)+(4*0)+(3*4)+(2*9)+(1*8)=213
213 % 10 = 3
So 869304-98-3 is a valid CAS Registry Number.

Synthesis of non-symmetric bisoxazoline compounds. An easy way to reach tailored chiral ligands

Garcia, Jose I.,Mayoral, Jose A.,Pires, Elisabet,Villalba, Isabel

, p. 2270 - 2275 (2007/10/03)

Bisoxazoline compounds have been used as chiral catalyst ligands in a wide variety of reactions. A great deal of effort has been aimed at the synthesis of C2-symmetric bisoxazolines but very few references exist for non-symmetric ones. As part of our studies into the possible usefulness of non-symmetric bisoxazolines, we report an easy method for the synthesis of bisoxazoline compounds bearing different substituents in each oxazoline ring.
