Check Digit Verification of cas no

The CAS Registry Mumber 875243-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,2,4 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 875243-46:
(8*8)+(7*7)+(6*5)+(5*2)+(4*4)+(3*3)+(2*4)+(1*6)=192
192 % 10 = 2
So 875243-46-2 is a valid CAS Registry Number.

Green photochemistry: Photo-Friedel-Crafts acylations of 1,4-naphthoquinone in room temperature ionic liquids

Murphy, Brian,Goodrich, Peter,Hardacre, Christopher,Oelgemoeller, Michael

, p. 1867 - 1870 (2009)

The photo-Friedel-Crafts acylation of 1,4-naphthoquinone with various aldehydes was investigated in a series of room temperature ionic liquids. High conversions and selectivities were achieved in [C2mim] +-based ionic liquids with the highest isolated yields found in [C2mim][NTf2]. The developed procedure allowed for a replacement of hazardous solvents such as benzene and acetonitrile which are commonly used for this transformation. The Royal Society of Chemistry 2009.
