78587-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78587-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,8 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78587-74:
(7*7)+(6*8)+(5*5)+(4*8)+(3*7)+(2*7)+(1*4)=193
193 % 10 = 3
So 78587-74-3 is a valid CAS Registry Number.

Synthesis of 2,6-Diaryl-1,4-oxathiin 4,4-Dioxides
Baliah, V.,Ganapathy, K.,Ananthapadmanabhan, S.
, p. 334 - 335 (2007/10/02)
Three new 2,6-diaryl-1,4-oxathiin 4,4-dioxides (IIa-c) have been synthesised by the cyclisation of the corresponding diaryl sulphones (1a-c) in the presence of POCl3 / Ac2O.Their UV and IR spectra indicate that the aryl groups are in planes different from
