1421029-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421029-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,0,2 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1421029-29:
(9*1)+(8*4)+(7*2)+(6*1)+(5*0)+(4*2)+(3*9)+(2*2)+(1*9)=109
109 % 10 = 9
So 1421029-29-9 is a valid CAS Registry Number.

Synthesis and properties of bisphosphole-bridged ladder oligophenylenes
Hanifi, David,Pun, Andrew,Liu, Yi
, p. 2615 - 2620,6 (2012)
Ladder-type oligophenylenes (LOPP) with bridging heteroatoms are interesting systems as they offer novel electronic and photophysical properties on account of the rigid structural features, more efficient electron delocalization on the coplanar aromatic f
