69146-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69146-81-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,4 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69146-81:
(7*6)+(6*9)+(5*1)+(4*4)+(3*6)+(2*8)+(1*1)=152
152 % 10 = 2
So 69146-81-2 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
