860032-69-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 860032-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,0,0,3 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 860032-69:
(8*8)+(7*6)+(6*0)+(5*0)+(4*3)+(3*2)+(2*6)+(1*9)=145
145 % 10 = 5
So 860032-69-5 is a valid CAS Registry Number.

Chemistry of phosphorus ylides. Part 25 [1]. Interaction of hexaphenylcarbodiphosphorane with carbonyls, hydrazone, and Mannich bases. A synthesis of phosphoranylidenes, phosphobetaines, and oxaphosphinin

Said, Medhat M.,Maigali, Soher S.,Abd-El-Maksoud, Mansoura A.,Soliman, Fouad M.

experimental part, p. 1299 - 1306 (2009/12/05)

The reaction of the allylic hexaphenylcarbodiphosphorane with carbonyls afforded the corresponding phosphoranylidene derivatives. On the other hand, the stable phosphorbetaines were obtained when the bisphosphorane was allowed to react with the α-diketone and triketone. The azaphosphoranylidene was isolated from the reaction of the bisphosphorane with hydrazone. Moreover, the bisphosphorane reacted with niclosamide and quinoline Mannich bases with the formation of the oxaphosphinins. When the Wittig reaction was performed with the new phosphoranes, the corresponding exocyclic olefins were obtained. On the other hand, the oxaphosphinins were produced when the phosphoranes were treated under the condition of a Hoffmann degradation reaction.
