39857-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39857-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,5 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39857-79:
(7*3)+(6*9)+(5*8)+(4*5)+(3*7)+(2*7)+(1*9)=179
179 % 10 = 9
So 39857-79-9 is a valid CAS Registry Number.

Synthetic attempts towards polymer-bound 'push-pull' acetylenes
Wilhelm, Patrick,Neuenschwander, Markus
, p. 338 - 346 (2007/10/03)
In view of possible applications of 'push-pull' acetylenes 1 and 'push- pull' olefins 2 as potential non-linear optics materials, synthetic attempts towards polymers of type 4 and 6 (Scheme 2) have been undertaken. Two so far unknown 'push-pull' acetylene
