Check Digit Verification of cas no

The CAS Registry Mumber 144889-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,8 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144889-77:
(8*1)+(7*4)+(6*4)+(5*8)+(4*8)+(3*9)+(2*7)+(1*7)=180
180 % 10 = 0
So 144889-77-0 is a valid CAS Registry Number.

A facile synthesis of unsymmetrical diaryl sulfones under triphase phase-transfer catalysis

Srinivasan,Kumar,Ayyangar

, p. 825 - 826 (1992)

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.
