Check Digit Verification of cas no

The CAS Registry Mumber 697248-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,7,2,4 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 697248-56:
(8*6)+(7*9)+(6*7)+(5*2)+(4*4)+(3*8)+(2*5)+(1*6)=219
219 % 10 = 9
So 697248-56-9 is a valid CAS Registry Number.

Synthesis of ABC 3-miktoarm star terpolymers from a trifunctional initiator by combining ring-opening polymerization, atom transfer radical polymerization, and nitroxide-mediated radical polymerization

He, Tao,Li, Dejin,Sheng, Xia,Zhao, Bin

, p. 3128 - 3135 (2004)

We report a new method to synthesize ABC 3-miktoarm star terpolymers by combining three different controlled/"living" polymerization techniques: ring-opening polymerization (ROP), atom transfer radical polymerization (ATEP), and nitroxide-mediated radical
