Check Digit Verification of cas no
The CAS Registry Mumber 1133079-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,0,7 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1133079-40:
(9*1)+(8*1)+(7*3)+(6*3)+(5*0)+(4*7)+(3*9)+(2*4)+(1*0)=119
119 % 10 = 9
So 1133079-40-9 is a valid CAS Registry Number.

Synthesis of 1-arylcyclopropylphosphonates
Gulyukina,Varakuta,Beletskaya
, p. 1884 - 1890 (2008/09/20)
A simple method for the synthesis of 1-arylcyclopropylphosphonates was proposed. The method involves treatment of 1-arylethenylphosphonic acids or their esters with diazomethane followed by thermolysis of intermediate 3-aryl-4,5-dihydro-3H-pyrazol-3-ylphosphonates.
