Check Digit Verification of cas no

The CAS Registry Mumber 56893-14-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,8,9 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56893-14:
(7*5)+(6*6)+(5*8)+(4*9)+(3*3)+(2*1)+(1*4)=162
162 % 10 = 2
So 56893-14-2 is a valid CAS Registry Number.

Synthesis of trifluoromethyl-/cyclopropyl-substituted 2-isoxazolines by DBU-promoted domino reaction

Liu, Xiao-Dong,Ma, Hai-Yan,Xing, Chun-Hui,Lu, Long

supporting information, p. 1780 - 1783 (2017/07/27)

NTrifluoromethyl and cyclopropyl substituted 2-isoxazolines were synthesized via a DBU-promoted domino reaction of β-trifluoromethyl-/β-cyclopropyl-substituted enones with hydroxylamine. The domino reaction consists of a Michael addition and the followed cyclization. A wide range of 3-substituted 5-cyclopropyl-5- trifluoromethyl-2-isoxazolines were obtained in good to excellent yields under mild reaction conditions. The method could also apply to other trifluoromethyl-substituted enones.
