Check Digit Verification of cas no
The CAS Registry Mumber 131170-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 131170-48:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*0)+(2*4)+(1*8)=84
84 % 10 = 4
So 131170-48-4 is a valid CAS Registry Number.

A general approach to unsymmetrical tricoordinate iodinanes: Single step preparation of mixed iodosobenzene sulfonates Phl(X)OSO2R, via reaction of iodosobenzene with Me3SiX
Zhdankin, Viktor V.
, p. 4821 - 4824 (1990)
Mixed iodonium sulfonates of the type Phl(X)OSO2R (X = OAc, NHAc, NCO, CN; R = CF3, C4F9, p-CH3C6H4) have been prepared by the reaction of PhlO with the appropriate derivatives of trimethylsilane.
