131588-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131588-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,8 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131588-80:
(8*1)+(7*3)+(6*1)+(5*5)+(4*8)+(3*8)+(2*8)+(1*0)=132
132 % 10 = 2
So 131588-80-2 is a valid CAS Registry Number.

Cyclopentadienes 1 react with diaryl disulfides 2 to form the tetrakis(arylthio)cyclopentadienides 3, which have been oxidized with m-chloroperbenzoic acid to give the tetrakis(arylsulfonyl)cyclopentadienides 5.Protonation of 5 yields the tetrakis(arylsul
