74724-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74724-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,2 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74724-80:
(7*7)+(6*4)+(5*7)+(4*2)+(3*4)+(2*8)+(1*0)=144
144 % 10 = 4
So 74724-80-4 is a valid CAS Registry Number.

New Reagents, XXXIII, Synthesis of (Diphenylbismutino)methyllithium and its Reactions with Carbonyl Compounds

Kauffmann, Thomas,Steinseifer, Fritz,Klas, Norbert

, p. 1039 - 1044 (2007/10/02)

Bis(diphenylbismutino)methane (3; yield max. 53percent) was synthesized for the first time.By the reaction with phenyllithium it gave (diphenylbismutino)methyllithium (4; ca. 70percent).This thermolabile compound (half-live period ca. 34 min at 25 deg C) reacts at -78 deg C with aldehydes and benzophenone.The adducts are decomposed by HClO4 to give alkenes.Hydrolysis with water of the benzophenone adduct gave 2-(diphenylbismutino)-1,1-diphenylethanol (7; 48percent).
