1443202-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1443202-22-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,2,0 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1443202-22:
(9*1)+(8*4)+(7*4)+(6*3)+(5*2)+(4*0)+(3*2)+(2*2)+(1*2)=109
109 % 10 = 9
So 1443202-22-9 is a valid CAS Registry Number.

Silicon-induced phenanthrene formation from benzynes and allenylsilanes
Hwu, Jih Ru,Swain, Sharada P.
, p. 6556 - 6560 (2013/06/27)
Now directly feasible: The silicon atom in allenylsilanes enabled their reaction with two equivalents of benzynes to generate (α-phenanthrenyl) vinylsilanes in good to excellent yields through an unprecedented [2+2+2] pathway (see scheme). Copyright
