1313809-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313809-09-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,8,0 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1313809-09:
(9*1)+(8*3)+(7*1)+(6*3)+(5*8)+(4*0)+(3*9)+(2*0)+(1*9)=134
134 % 10 = 4
So 1313809-09-4 is a valid CAS Registry Number.

Molecular polygons with three to six sides and binary mixtures thereof form long-range ordered patterns at the TCB/HOPG interface. This includes also the 2D crystallization of pentagons. The results provide an insight into how the symmetry of molecules is
