Check Digit Verification of cas no

The CAS Registry Mumber 1174575-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,5,7 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1174575-80:
(9*1)+(8*1)+(7*7)+(6*4)+(5*5)+(4*7)+(3*5)+(2*8)+(1*0)=174
174 % 10 = 4
So 1174575-80-4 is a valid CAS Registry Number.

Hyperbranched polymers with a degree of branching of 100% prepared by catalyst transfer Suzuki-Miyaura polycondensation

Huang, Weiguo,Su, Linjie,Bo, Zhishan

, p. 10348 - 10349 (2009)

(Chemical Equation Presented) Hyperbranched polymers with a degree of branching of 100% were prepared by catalyst transfer Suzuki-Miyaura polymerization of AB2 monomers carrying one boronic acid and two aromatic bromo functional groups; in contrast, Suzuki-Miyaura polymerization of the same AB2 monomers using a traditional catalyst afforded hyperbranched polymers with a branching degree of only ～56%. This is a nice example of controlling the topology of hyperbranched polymers via the catalyst.
