196106-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 196106-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,1,0 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 196106-29:
(8*1)+(7*9)+(6*6)+(5*1)+(4*0)+(3*6)+(2*2)+(1*9)=143
143 % 10 = 3
So 196106-29-3 is a valid CAS Registry Number.

Preparation of sterically constrained arylalkynes
Crisp, Geoffrey T.,Bubner, Timothy P.
, p. 11881 - 11898 (2007/10/03)
The preparation of a series of sterically constrained phenyleneethynylenes is described. Restricting the interannular rotation significantly narrows the lowest energy absorption and increases its extinction coefficient in the UV/VIS spectrum.
