Check Digit Verification of cas no

The CAS Registry Mumber 850223-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,2,2 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 850223-45:
(8*8)+(7*5)+(6*0)+(5*2)+(4*2)+(3*3)+(2*4)+(1*5)=139
139 % 10 = 9
So 850223-45-9 is a valid CAS Registry Number.

Cross-couplings between benzylic and aryl halides on water : Synthesis of diarylmethanes

Duplais, Christophe,Krasovskiy, Arkady,Wattenberg, Alina,Lipshutz, Bruce H.

, p. 562 - 564 (2010)

A remarkably simple entry to unsymmetrical diarylmethanes has been developed that relies on an in situ organozinc-mediated, palladium-catalyzed cross-coupling. Thus, by mixing a benzyl and aryl halide together in the presence of Zn metal and a Pd catalyst, diarylmethanes are formed at room temperature without assistance by a surfactant; hence, on water .
