72041-42-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72041-42-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,4 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72041-42:
(7*7)+(6*2)+(5*0)+(4*4)+(3*1)+(2*4)+(1*2)=90
90 % 10 = 0
So 72041-42-0 is a valid CAS Registry Number.

The photolytic disproportionation of dialkyl 2,2-di(phenylseleno)propanedioates
Byers,Thissell
, p. 21 - 26 (1995)
Dialkyl-2,2-di(phenylseleno)propanedioates undergo disproportionation to form tetralkyl 1,1,2,2-ethylene tetracarboxylates and diphenyl diselenide upon photolysis. Evidence for the intermediacy of a capto-dative radical intermediate in this process is described.
