855839-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 855839-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,8,3 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 855839-41:
(8*8)+(7*5)+(6*5)+(5*8)+(4*3)+(3*9)+(2*4)+(1*1)=217
217 % 10 = 7
So 855839-41-7 is a valid CAS Registry Number.

Synthesis of substituted carbazoles, indoles, and dibenzofurans by vinylic to aryl palladium migration
Zhao, Jian,Larock, Richard C.
, p. 5340 - 5348 (2006)
Substituted carbazoles, indoles, and dibenzofurans are readily prepared in moderate to excellent yields by the palladium-catalyzed cross-coupling of alkynes and appropriately substituted aryl iodides. This process proceeds by carbopalladation of the alkyn
