89244-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89244-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,4 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89244-53:
(7*8)+(6*9)+(5*2)+(4*4)+(3*4)+(2*5)+(1*3)=161
161 % 10 = 1
So 89244-53-1 is a valid CAS Registry Number.

THE DILITHIATION MECHANISM IN THE REACTIONS OF POLYHALOARENES AS DI-ARYNE EQUIVALENTS
Hart, Harold,Nwokogu, Godson C.
, p. 5721 - 5724 (2007/10/02)
The preparation of certain 1,4-dilithio-tetrahaloarenes is described; they react with electrophiles at low temperatures or form arynes at higher temperatures.
