(4-(benzoyloxy)butyl)triphenylphosphonium bromide is a chemical compound with the molecular formula C31H29O2PBr. It is a quaternary phosphonium salt that is commonly used as a phase-transfer catalyst in organic synthesis. The compound is a white to off-white powder and is highly soluble in polar solvents such as ethanol and methanol. It is often employed in reactions that involve the transfer of anions from one phase to another, and it has been shown to be effective in promoting the alkylation, acylation, and halogenation of various organic substrates. Additionally, it has been found to be an effective catalyst in the synthesis of various pharmaceutical and agrochemical intermediates. Despite being a powerful catalyst, (4-(benzoyloxy)butyl)triphenylphosphonium bromide is relatively non-toxic and is considered to be safe for use in laboratory settings.
Check Digit Verification of cas no
The CAS Registry Mumber 70359-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70359-30:
(7*7)+(6*0)+(5*3)+(4*5)+(3*9)+(2*3)+(1*0)=117
117 % 10 = 7
So 70359-30-7 is a valid CAS Registry Number.
