Check Digit Verification of cas no

The CAS Registry Mumber 75590-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75590-20:
(7*7)+(6*5)+(5*5)+(4*9)+(3*0)+(2*2)+(1*0)=144
144 % 10 = 4
So 75590-20-4 is a valid CAS Registry Number.

Reactions of Carbanions with Carbon Tetrachloride in Two-Phase Systems. Chlorinated Products as Nucleophilic and Electrophilic Intermediates

Makosza, M.,Kwast, A.,Kwast, E.,Jonczyk, A.

, p. 3722 - 3727 (2007/10/02)

A variety of carbanions generated in the catalytic two-phase system (aqueous NaOH or K2CO3 and tetrabutylammonium bromide catalyst) react with CCl4 to form chlorinated products that can react as nucleophiles and electrophiles.Thus, chlorinated intermediates generated from arylacetonitriles and propiophenone in the presence of aldehydes and electrophilic alkenes form oxirane and cyclopropane derivatives, respectively.The chlorinated intermediates act as electrophiles toward Cl3C- giving (trichloromethyl)oxiranes (from aryl alkyl ketones), α-trichloromethyl nitriles (from phenyl(dialkylamino)acetonitriles), and benzoyldichloro enamines (from α-dialkylamino ketones).From secondary nitroalkanes both chloronitroalkanes and dinitro compounds can be produced.
