131254-45-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131254-45-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,5 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131254-45:
(8*1)+(7*3)+(6*1)+(5*2)+(4*5)+(3*4)+(2*4)+(1*5)=90
90 % 10 = 0
So 131254-45-0 is a valid CAS Registry Number.

Catalytic self-threading: A new route for the synthesis of polyrotaxanes
Tuncel, Doenues,Steinke, Joachim H. G.
, p. 288 - 302 (2004)
Main chain and branched polyrotaxanes have been synthesized in which polymerization and rotaxane formation occur simultaneously, due to the presence of the catalytically active self-threading macrocycle cucurbit[6]uril. Using monomers that contain stopper
