Check Digit Verification of cas no
The CAS Registry Mumber 77257-24-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,5 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77257-24:
(7*7)+(6*7)+(5*2)+(4*5)+(3*7)+(2*2)+(1*4)=150
150 % 10 = 0

Dimethylaluminum Chloride Catalyzed Reactions of Methyl α-Cyanoacrylate with Alkenes
Snider, Barry B.,Phillips, Gary B.
, p. 2563 - 2566 (1981)
The methyl α-cyanoacrylate-Me2AlCl complex reacts with alkenes to give zwitterion 2.Ring closure on carbon gives the cyclobutane 3 with ca. 90percent retention of alkene stereochemistry, ring closure on oxygen gives dihydropyran 5, and a 1,5-hydrogen shif
