Check Digit Verification of cas no
The CAS Registry Mumber 63785-39-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,7,8 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63785-39:
(7*6)+(6*3)+(5*7)+(4*8)+(3*5)+(2*3)+(1*9)=157
157 % 10 = 7
So 63785-39-7 is a valid CAS Registry Number.

Chain stopper-assisted characterization of supramolecular polymers
Lortie, Frederic,Boileau, Sylvie,Bouteiller, Laurent,Chassenieux, Christophe,Laupretre, Francoise
, p. 5283 - 5287 (2005)
Supramolecular polymers are dynamic materials; consequently, their molar mass is concentration dependent. However, the present experimental results show that an efficient chain stopper (i.e., a monofunctional monomer) can be used to block the concentratio
