549529-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 549529-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,9,5,2 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 549529-18:
(8*5)+(7*4)+(6*9)+(5*5)+(4*2)+(3*9)+(2*1)+(1*8)=192
192 % 10 = 2
So 549529-18-2 is a valid CAS Registry Number.

, p. 2307 - 2310 (2007/10/03)
A bifunctional [2]rotaxane, bearing two free functional groups each in the ring and axial parts, was synthesized, followed by its polycondensation with methylene diphenyl diisocyanate leading to a mechanically linked oligo[2]rotaxane.
