7646-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7646-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7646-81:
(6*7)+(5*6)+(4*4)+(3*6)+(2*8)+(1*1)=123
123 % 10 = 3
So 7646-81-3 is a valid CAS Registry Number.

Direct, oxidative halogenation of diaryl- or dialkylphosphine oxides with (dihaloiodo)arenes

Eljo, Jasmin,Murphy, Graham K.

supporting information, p. 2965 - 2969 (2018/06/30)

The oxidative halogenation of diaryl- or dialkylphosphine oxides with the hypervalent iodine reagents (difluoroiodo)toluene (p-TolIF2, 1) and (dichloroiodo)benzene (PhICl2, 2) is reported. Phosphoric fluorides could be recovered in 32–75% yield, or they could be trapped with EtOH to give the corresponding phosphinate in typically good yield. Phosphoric chlorides were not readily isolable, and were trapped with alcohol and amine nucleophiles, giving diaryl- or dialkylphos-phinates and phosphinamides in up to 90% yield.

Reactivity of diacyloxyiodobenzenes toward trivalent phosphorus nucleophiles

Makowiec, Slawomir,Rachon, Janusz

, p. 352 - 359 (2007/10/03)

The reaction of diacyloxyiodobenzenes and tetravalent phosphorus nucleophiles was investigated. It was established that both H-phosphonates and secondary phosphine oxides react with diacetoxyiodobenzene in alcohols in the presence of sodium alcoholates yi
