87274-16-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87274-16-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,7 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87274-16:
(7*8)+(6*7)+(5*2)+(4*7)+(3*4)+(2*1)+(1*6)=156
156 % 10 = 6
So 87274-16-6 is a valid CAS Registry Number.

Synthesis of cyclobutanes by lewis acid-promoted ketene-alkene [2+2] cycloadditions
Rasik, Christopher M.,Salyers, Eleni M.,Brown, M. Kevin
, (2018/11/21)
When compared to thermally-induced reactions, Lewis acid-promoted variants give rise to increased yields for unactivated alkenes. The article describes the synthesis of cyclobutanes by Lewis acid-promoted ketene-alkene [2+2] cycloadditions.
