Triphenylsiloxy-tripropyl-zinn, also known as (tripropyl-zinn)triphenylsilanolato-zinn, is a complex organometallic compound with the chemical formula [Sn(C3H7)3]2[Sn(C6H5)3]2SiO. Triphenylsiloxy-tripropyl-zinn consists of two tripropyltin (Sn(C3H7)3) and two triphenyltin (Sn(C6H5)3) units bridged by a siloxy (SiO) group. It is a white crystalline solid and is used as a catalyst in various organic reactions, particularly in the hydrosilylation process, where it promotes the addition of silicon-hydrogen bonds to carbon-carbon double bonds. The compound is sensitive to air and moisture, and it is typically stored under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 16524-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,2 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16524-81:
(7*1)+(6*6)+(5*5)+(4*2)+(3*4)+(2*8)+(1*1)=105
105 % 10 = 5
So 16524-81-5 is a valid CAS Registry Number.
