Check Digit Verification of cas no
The CAS Registry Mumber 357-28-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 357-28:
(5*3)+(4*5)+(3*7)+(2*2)+(1*8)=68
68 % 10 = 8
So 357-28-8 is a valid CAS Registry Number.

(Z) -Trifluoromethyl-Trisubstituted Alkenes or Isoxazolines: Divergent Pathways from the Same Allene
Liu, Chaolun,Rowland, Casey A.,Tius, Marcus A.,Yap, Glenn P. A.
supporting information, p. 7208 - 7212 (2020/10/02)
Because of a charge-dipole interaction involving nonbonding electron pairs on fluorine, protonation of trifluoromethyl allenes leads to tri- or tetrasubstituted alkenes with high (Z)-selectivity. Treatment of the same allenes with catalytic Au(I) initiates a reaction cascade that produces isoxazolines in high yield.
