Check Digit Verification of cas no

The CAS Registry Mumber 141407-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,4,0 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141407-30:
(8*1)+(7*4)+(6*1)+(5*4)+(4*0)+(3*7)+(2*3)+(1*0)=89
89 % 10 = 9
So 141407-30-9 is a valid CAS Registry Number.

Sulfonyl chloride as a disposable electron withdrawing substituent in halex fluorinations

Kageyama, Hiroyuki,Suzuki, Hiroshi,Kimura, Yoshikazu

, p. 85 - 89 (2000)

Syntheses of 1,3-difluorobenzene and 2,6-difluorotoluene are described via chlorosulfonation, catalytic Halex-fluorination, and desulfination of 1,3-dichlorobenzene and 2,6-dichlorotoluene.

Tetraphenylphosphonium bromide-catalyzed 'Halex' fluorination of chloroaryl sulfonyl chlorides

Suzuki, Hiroshi,Kageyama, Hiroyuki,Yoshida, Yasuo,Kimura, Yoshikazu

, p. 335 - 337 (2007/10/02)

Halogen-exchange of chloroaryl sulfonylchloride derivatives with spray-dried potassium fluoride was found to proceed efficiently by employing tetraphenylphosphonium bromide as a catalyst.Subsequent desulfonylation of the fluoroaryl sulfonyl derivatives readily afforded fluoroaromatics under acidic condition.
