3666-89-5 Usage
General Description
Cyclobutyltriphenylphosphonium bromide is a chemical compound with the formula C23H25BrP. It is a phosphonium salt, which is commonly used as a phase-transfer catalyst in organic synthesis. The cyclobutyl group attached to the phosphonium ion makes this compound particularly useful for promoting nucleophilic substitution reactions. The bromide anion serves as a counterion to balance the positive charge of the phosphonium cation. Cyclobutyltriphenylphosphonium bromide is a white to off-white crystalline solid that is typically handled and stored in air-tight containers to prevent moisture and air exposure.
Check Digit Verification of cas no
The CAS Registry Mumber 3666-89-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3666-89:
(6*3)+(5*6)+(4*6)+(3*6)+(2*8)+(1*9)=115
115 % 10 = 5
So 3666-89-5 is a valid CAS Registry Number.
