1323441-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1323441-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,3,4,4 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1323441-18:
(9*1)+(8*3)+(7*2)+(6*3)+(5*4)+(4*4)+(3*1)+(2*1)+(1*8)=114
114 % 10 = 4
So 1323441-18-4 is a valid CAS Registry Number.

A noncovalently assembled porphyrinic catenane consisting of two interlocking [43]-membered rings
Beyler, Maryline,Heitz, Valerie,Sauvage, Jean-Pierre
, p. 1751 - 1757 (2011)
A new macrocycle and the corresponding [2]catenane were prepared quantitatively from relatively large organic fragments using coordination chemistry bonds only (Zn-N bonds for the ring and Cu-N bonds for the catenane). The two constitutive macrorings of t
