2412-05-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2412-05-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2412-05:
(6*2)+(5*4)+(4*1)+(3*2)+(2*0)+(1*5)=47
47 % 10 = 7
So 2412-05-7 is a valid CAS Registry Number.

A facile synthesis of unsymmetrical diaryl sulfones under triphase phase-transfer catalysis
Srinivasan,Kumar,Ayyangar
, p. 825 - 826 (2007/10/02)
Unsymmetrical diaryl sulfones having electron-withdrawing substituents have been synthesized from arenesulfonyl chlorides and activated 4-chloro-3-nitroarenes in excellent yield under triphase phase-transfer catalytic conditions.
