Check Digit Verification of cas no

The CAS Registry Mumber 15731-93-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,3 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15731-93:
(7*1)+(6*5)+(5*7)+(4*3)+(3*1)+(2*9)+(1*3)=108
108 % 10 = 8
So 15731-93-8 is a valid CAS Registry Number.

Organocatalytic Enantioselective 1,6-aza-Michael Addition of Isoxazolin-5-ones to p-Quinone Methides

Torán, Ricardo,Vila, Carlos,Sanz-Marco, Amparo,Mu?oz, M. Carmen,Pedro, José R.,Blay, Gonzalo

supporting information, p. 627 - 630 (2020/02/05)

A thiourea-Br?nsted base bifunctional catalyst allowed the enantioselective 1,6-aza-Michael addition of isoxazolin-5-ones to p-quinone methides to give isoxazolin-5-ones having a chiral diarylmethyl moiety attached to the N atom with fair to good yields and enantiomeric excesses. To the best of our knowledge this reaction represents the first example of enantioselective N-alkylation of isoxazolin-5-ones as well as the first example of enantioselective 1,6-aza-Michael reaction involving p-quinone methides.
