Check Digit Verification of cas no
The CAS Registry Mumber 38439-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,3 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38439-93:
(7*3)+(6*8)+(5*4)+(4*3)+(3*9)+(2*9)+(1*3)=149
149 % 10 = 9
So 38439-93-9 is a valid CAS Registry Number.

Ruthenium-catalyzed knoevenagel condensation: A new route toward cyano-substituted poly(p-phenylenevinylene)s
Liao, Jian,Wang, Qing
, p. 7061 - 7063 (2007/10/03)
The ruthenium-catalyzed Knoevenagel reaction was developed for the preparation of cyano-substituted conjugated polymers. The polymerization was quenched by pouring the reaction mixture into methanol. The structures of polymers were confirmed by spectroscopic studies and elemental analysis. The results show that Knoevenagel polycondensation mediated by transition metal complexes enjoys the advantages of neutral and mild reaction conditions.
