141793-24-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141793-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,9 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141793-24:
(8*1)+(7*4)+(6*1)+(5*7)+(4*9)+(3*3)+(2*2)+(1*4)=130
130 % 10 = 0
So 141793-24-0 is a valid CAS Registry Number.

Novel metal-free Lewis acid catalysis by phosphonium salts through hypervalent interaction
Terada, Masahiro,Kouchi, Mitsuhiro
, p. 401 - 409 (2006)
Phosphonium salts as a novel metal-free Lewis acid catalyst can be considered as organocatalysts. The introduction of a five-membered dioxaphosphacycle to the phosphonium salt is critical to its function as a Lewis acid catalyst for the Diels-Alder reacti
