Check Digit Verification of cas no

The CAS Registry Mumber 1353883-61-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,8,8 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1353883-61:
(9*1)+(8*3)+(7*5)+(6*3)+(5*8)+(4*8)+(3*3)+(2*6)+(1*1)=180
180 % 10 = 0
So 1353883-61-0 is a valid CAS Registry Number.

Synthesis of fluorine-containing multisubstituted phenanthridines by rhodium-catalyzed alkyne [2+2+2] cycloaddition and tandem sp2 C-H difluoromethylenation

, p. 8294 - 8299 (2013/07/27)

A highly efficient method for the synthesis of fluorine-containing multisubstituted phenanthridines through Rh-catalyzed alkyne [2+2+2] cycloaddition reactions has been developed. This method exhibits excellent functional-group compatibility. When a bromodifluoromethyl group, rather than a trifluoromethyl group, was employed in the cycloaddition reaction, more-complicated polycyclic compounds were obtained through tandem Rh-catalyzed cycloaddition/C-H difluoromethylenation. This route provides convenient access to fluorine-containing polycyclic compounds. [2+2+2] Little boys: Fluorine-containing multisubstituted phenanthridines have been synthesized through Rh-catalyzed alkyne [2+2+2] cycloaddition reactions (see scheme; FG=functional group). Polycyclic compounds were also obtained through Rh-catalyzed C-H difluoromethylenation. Copyright
