473702-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 473702-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,7,0 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 473702-71:
(8*4)+(7*7)+(6*3)+(5*7)+(4*0)+(3*2)+(2*7)+(1*1)=155
155 % 10 = 5
So 473702-71-5 is a valid CAS Registry Number.

Synthesis of a strapped calix[4]pyrrole: Structure and anion binding properties
Yoon, Dae-Wi,Hwang, Hoon,Lee, Chang-Hee
, p. 1757 - 1759 (2007/10/03)
Enhanced affinity and selectivity for halide anions is seen for the strapped calix[4]pyrrole (see picture, X-=F-, Cl-) relative to normal calix[4]pyrroles. The encapsulated binding site differentiates the anions on the bas
