Check Digit Verification of cas no
The CAS Registry Mumber 190728-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,2 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 190728-73:
(8*1)+(7*9)+(6*0)+(5*7)+(4*2)+(3*8)+(2*7)+(1*3)=155
155 % 10 = 5
So 190728-73-5 is a valid CAS Registry Number.

General strategy for the synthesis of natural and unnatural dialkylmaleic anhydrides
Haval, Kishan P.,Argade, Narshinha P.
, p. 6936 - 6938 (2008/12/22)
(Chemical Equation Presented) Starting from alkylidenesuccinimides, a wide range of dialkylmaleic anhydrides have been synthesized via the generation of a carbanion on a succinimide unit and its condensation with various alkyl halides as the key reaction.
