72939-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72939-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,3 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72939-12:
(7*7)+(6*2)+(5*9)+(4*3)+(3*9)+(2*1)+(1*2)=149
149 % 10 = 9
So 72939-12-9 is a valid CAS Registry Number.

Memory of Synthesized Vinyl Polymers for Their Origins
Damen, Julien,Neckers, D. C.
, p. 1382 - 1387 (1980)
We report studies on the memory of a highly cross-linked styrene-divinylbenzene copolymer for its origins.Specific experiments are described which indicate that vinyl polymers synthesized from diastereoisomers of truxinic and truxillic acid are able to re
