87593-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87593-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,9 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87593-53:
(7*8)+(6*7)+(5*5)+(4*9)+(3*3)+(2*5)+(1*3)=181
181 % 10 = 1
So 87593-53-1 is a valid CAS Registry Number.

SYNTHESIS OF 3-PHENYLTHIOCHROMONES FROM 2'-HYDROXY-2-PHENYLTHIOACETOPHENONES
Szabo, V.,Kiss, A.
, p. 193 - 200 (2007/10/02)
2'-Hydroxy-2-phenylthioacetophenone derivatives (4a, b) can be readily prepared either from 2'-hydroxy-2-halogenoacetophenones (1a-c) and thiophenol, or from phenylthioacetonitrile and polyphenols (route 4b, c).The partial methylation reaction of 4b is co
