57004-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57004-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,0 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57004-22:
(7*5)+(6*7)+(5*0)+(4*0)+(3*4)+(2*2)+(1*2)=95
95 % 10 = 5
So 57004-22-5 is a valid CAS Registry Number.

SYNTHESIS AND REACTIVITY OF DISULFONYL CHLORIDES FROM 1,1,1-TRICHLORO-2,2-BIS(4-CHLOROPHENYL)ETHANE
Novakovski, E.
, p. 1319 - 1322 (2007/10/02)
The corresponding disulfonyl chlorides, sodium disulfonates, and disulfonamides were obtained from 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane and its analogs by successive chlorosulfonation, hydrolysis, salting out, and ammonolysis.
