182355-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182355-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,3,5 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 182355-90:
(8*1)+(7*8)+(6*2)+(5*3)+(4*5)+(3*5)+(2*9)+(1*0)=144
144 % 10 = 4
So 182355-90-4 is a valid CAS Registry Number.

Synthesis of unsymmetrical calix[4]arene cryptand crown-6 in 1,3-alternate conformation
Pulpoka, Buncha,Asfari, Zouhair,Vicens, Jacques
, p. 6315 - 6318 (2007/10/03)
We report the synthesis of a calix[4]arene bridged by a cryptand unit and a crown ether chain in 1,3-alternate conformation. Preliminary complexation properties with alkali metals are also described.
