Check Digit Verification of cas no
The CAS Registry Mumber 7180-62-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7180-62:
(6*7)+(5*1)+(4*8)+(3*0)+(2*6)+(1*2)=93
93 % 10 = 3
So 7180-62-3 is a valid CAS Registry Number.

A New Approach to Rethrolone Synthesis
Jondiko, Isaac J. O.,Pattenden, Gerald
, p. 467 - 470 (2007/10/02)
Rearrangement of the 4-ylidenebutenolides (4) and (5), with sodium methoxide in methanol, leads to the cyclopent-2-ene-1,4-diones (6), which when heated with sodium chloride in dimethyl sulphoxide give the 1,4-diones (7).The latter can be reduced using zinc in acetic acid, to the dihydroethrolones (8).In a similar manner, rearrangement of (10) produces (11a) which can be demethoxycarbonylated to (11b), an intermediate used previously in a synthesis of natural jasmololone (8; R = EtCH:CH).
