103762-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103762-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,6 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103762-82:
(8*1)+(7*0)+(6*3)+(5*7)+(4*6)+(3*2)+(2*8)+(1*2)=109
109 % 10 = 9
So 103762-82-9 is a valid CAS Registry Number.

Synthesis of ar-E-Atlantone
Anand, R. C.,Ranjan, H.
, p. 560 (2007/10/02)
Reformatsky reaction of p-methylacetophenone with 4-bromo-3-ethoxy-2-butanoate furnishes 4-ethoxy-6-methyl-6-p-tolyl-5,6-dihydropyran-2-one (V).Treatment of V with excess of methylmagnesium iodide gives the diol (VI) which on stirring with perchloric acid in ether affords ar-E-atlantone (I).
