1056457-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1056457-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,6,4,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1056457-31:
(9*1)+(8*0)+(7*5)+(6*6)+(5*4)+(4*5)+(3*7)+(2*3)+(1*1)=148
148 % 10 = 8
So 1056457-31-8 is a valid CAS Registry Number.

Benzodichalcogenophenes with Perfluoroarene Termini
Wang, Yongfeng,Parkin, Sean R.,Watson, Mark D.
supporting information; experimental part, p. 4421 - 4424 (2009/05/11)
(Chemical Equation Presented) Benzodichalcogenophenes are functionalized at their termini via SNAr reactions of their bismetalates with perfluoroarenes. The identities of X, Y, and W are varied to study the effects on LUMO energy levels and cry
