73838-81-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73838-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,3 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73838-81:
(7*7)+(6*3)+(5*8)+(4*3)+(3*8)+(2*8)+(1*1)=160
160 % 10 = 0
So 73838-81-0 is a valid CAS Registry Number.

Mercury in Organic Chemistry. 18. Synthesis of Symmetrical Divinyl and Diaryl Ketones via Rhodium-Catalyzed Carbonylation of Vinyl- and Arylmercurials

Larock, Richard C.,Hershberger, Susan S.

, p. 3840 - 3846 (1980)

Vinylmercuric chlorides readily react with rhodium(I) and rhodium(III) catalysts and carbon monoxide to give excellent yields of divinyl ketones.The best reaction conditions are 0.5 mol percent 2 and 2 equiv of lithium chloride under 1 atm of carbon monoxide at room temperature.This rhodium catalyst also provides improved yields of diaryl ketones from arylmercurials at 70 deg C under 1000-1500 psi of carbon monoxide pressure.Organorhodium compounds are presumed to be intermediates in these reactions.
