87768-45-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87768-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,6 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87768-45:
(7*8)+(6*7)+(5*7)+(4*6)+(3*8)+(2*4)+(1*5)=194
194 % 10 = 4
So 87768-45-4 is a valid CAS Registry Number.

Branch-selective, Iridium-catalyzed hydroarylation of monosubstituted alkenes via a cooperative destabilization strategy

Crisenza, Giacomo E. M.,McCreanor, Niall G.,Bower, John F.

, p. 10258 - 10261 (2014/08/05)

Highly branch-selective, carbonyl-directed hydroarylations of monosubstituted alkenes are described. The chemistry relies upon a cationic Ir(I) catalyst modified with an electron deficient, wide bite angle bisphosphine ligand. This work provides a regioisomeric alternative to the Murai hydroarylation protocol.

An efficient large scale synthesis of 4-isopropyl- and 4-isopropyl-6-methoxybenzisothiazolones

Desai,Hlasta,Monsour,Saindane

, p. 7161 - 7163 (2007/10/02)
