Check Digit Verification of cas no

The CAS Registry Mumber 181708-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,7,0 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 181708-51:
(8*1)+(7*8)+(6*1)+(5*7)+(4*0)+(3*8)+(2*5)+(1*1)=140
140 % 10 = 0
So 181708-51-0 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.
