The CAS Registry Mumber 15581-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,8 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15581-15:
(7*1)+(6*5)+(5*5)+(4*8)+(3*1)+(2*1)+(1*5)=104
104 % 10 = 4
So 15581-15-4 is a valid CAS Registry Number.

A three-component approach to isoxazolines and isoxazoles under metal-free conditions

Wang, Dahan,Zhang, Feng,Xiao, Fuhong,Deng, Guo-Jun

, p. 9163 - 9168 (2019)

A 1,3-dipolar cycloaddition of 2-methylquinoline, tert-butyl nitrite (TBN) and alkynes or alkenes for the synthesis of biheteroaryls containing both isoxazoline/isoxazole and quinoline motifs has been developed. In this protocol, TBN serves as a convenient N-O source to convert 2-methylquinoline into intermediate nitrile oxides in situ.
