194939-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194939-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,9,3 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 194939-13:
(8*1)+(7*9)+(6*4)+(5*9)+(4*3)+(3*9)+(2*1)+(1*3)=184
184 % 10 = 4
So 194939-13-4 is a valid CAS Registry Number.

Tetraphenylstibonium arenesulfonates: Synthesis and structure
Sharutin,Sharutina,Panova,Bel'skii
, p. 476 - 482 (2008/10/08)
The reaction of pentaphenylantimony with arenesulfonic acids (molar ratio 1:1 or 2:1) in a toluene-alcohol solution (1:1) gives tetraphenylstibonium arenesulfonates in a yield of 80-90%. The structure of the synthesized compounds is determined by X-ray structural analysis.
