50598-38-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50598-38-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,5,9 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50598-38:
(7*5)+(6*0)+(5*5)+(4*9)+(3*8)+(2*3)+(1*8)=134
134 % 10 = 4
So 50598-38-4 is a valid CAS Registry Number.

Protolysis of Cyclopropanes with Geminal Electronegative Substituents
Kolsaker, Per,Jensen, Ann Kristin
, p. 345 - 353 (2007/10/02)
Cyclopropanes with geminal ester substituents decompose in anhydrous HClO4/benzene solutions to give substituted γ-lactones; e.g. dimethyl 3,3-dimethyl-2-phenylcyclopropane-1,1-dicarboxylate (1e) is stereospecifically transformed to trans-γ,γ-dimethyl-α-m
