Check Digit Verification of cas no
The CAS Registry Mumber 199786-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,8 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 199786-59:
(8*1)+(7*9)+(6*9)+(5*7)+(4*8)+(3*6)+(2*5)+(1*9)=229
229 % 10 = 9
So 199786-59-9 is a valid CAS Registry Number.

Functionalized AB-type monomers for Suzuki polycondensation
Frahn,Schluter
, p. 1301 - 1304 (2007/10/03)
A high yield synthesis of two phenylene and biphenylene derived AB-type monomers for Suzuki polycondensation is described. They carry solubilizing alkyl groups and free and methyl-protected hydroxy functional groups for further modifications.
