Check Digit Verification of cas no
The CAS Registry Mumber 24889-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,8 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 24889-15:
(7*2)+(6*4)+(5*8)+(4*8)+(3*9)+(2*1)+(1*5)=144
144 % 10 = 4
So 24889-15-4 is a valid CAS Registry Number.

Electrochemically induced oxidative rearrangement of alkylidenemalonates
Elinson, Michail N.,Feducovich, Sergey K.,Nikishin, Gennady I.
, p. 14529 - 14540 (2007/10/03)
Alkylidenemalonates capable of double bond migration being electrolyzed in methanol or ethanol in the presence of alkali metal halides in an undivided cell equipped with Fe cathode are transformed into 2-alkyl-3,3- dimethoxyalkane-1,2-dicarboxylates in 70-90% yield via electrochemically induced oxidative rearrangement. Acidification of the reaction mixture after the electrolysis leads to the formation of 2-alkyl-3-oxoalkane-1,1- dicarboxylates. In the case of isobutylidenemalonate, the electrolysis intermediate dimethyl 3,3-dimethyl-2-methoxy-cyclopropane-1,1-dicarboxylate was isolated in 70% yield.
