87127-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87127-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,2 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87127-31:
(7*8)+(6*7)+(5*1)+(4*2)+(3*7)+(2*3)+(1*1)=139
139 % 10 = 9
So 87127-31-9 is a valid CAS Registry Number.

, p. 150 - 153 (2007/10/02)
Condensation of arylmercaptans with 2-chloro-2'-hydroxy-5'-methylacetophenones yields 2-aryl-2'-hydroxy-5'-methylthioacetophenones (I) which on oxidation with excess of hydrogen peroxide (30percent) and gl. acetic acid give the β-ketosulphones (II).The la
