247237-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247237-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,2,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 247237-97:
(8*2)+(7*4)+(6*7)+(5*2)+(4*3)+(3*7)+(2*9)+(1*7)=154
154 % 10 = 4
So 247237-97-4 is a valid CAS Registry Number.

Sulfenylation of heterocyclic 1,3-dicarbonyl compounds
Schnell, Barbara,Kappe, Thomas
, p. 1147 - 1157 (2007/10/03)
Anions of heteroaromatic 1,3-dicarbonyl compounds, such as 4-hydoxy-2-quinolones and 4-hydroxy-coumarins, react in DMF in the presence of potassium carbonate with diaryl disulfides to yield 3-arylsulfenyl derivatives. The arylthiolate anions formed in thi
