Check Digit Verification of cas no

The CAS Registry Mumber 320342-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,3,4 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 320342-75:
(8*3)+(7*2)+(6*0)+(5*3)+(4*4)+(3*2)+(2*7)+(1*5)=94
94 % 10 = 4
So 320342-75-4 is a valid CAS Registry Number.

Transition-metal-free and base promoted C-C bond formationviaC-N bond cleavage of organoammonium salts

A transition-metal-free and base promoted C-C bond forming reaction of benzyl C(sp3)-H bond with organoammonium saltsviaC-N bond cleavage has been reported. Benzyl ammonium salts as well as cinnamyl ammonium salt could couple readily with various benzyl C(sp3)-H species, producing the corresponding products in moderate to excellent yields with good functional group tolerance. Late stage chemical manipulation enabled the specific 1,2-diarylethane structure of products transformed into useful olefin compoundsviadehydrogenation, which further demonstrated the utility of this reaction.
