57780-61-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57780-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,8 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57780-61:
(7*5)+(6*7)+(5*7)+(4*8)+(3*0)+(2*6)+(1*1)=157
157 % 10 = 7
So 57780-61-7 is a valid CAS Registry Number.

SYNTHESIS AND REARRANGEMENT OF DIARYL-HYDROXY-BENZOTHIOPHENS. A NEW SYNTHESIS OF 2,3-DIARYL-BENZOTHIOPHENS

Leardini, Rino,Tundo, Antonio,Zanardi, Giuseppe,Pedulli, Gianfranco

, p. 3381 - 3382 (2007/10/02)

The synthesis of some 2-hydroxy-2(H)-3,3-diaryl- and 3-hydroxy-3(H)-2,2-diaryl-benzothiophens (4) and (7) respectively is described; by acidic treatment these compounds readily rearrange to 2,3-diaryl-benzothiophens (5) in almost quantitative yields
