75233-43-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75233-43-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,3 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75233-43:
(7*7)+(6*5)+(5*2)+(4*3)+(3*3)+(2*4)+(1*3)=121
121 % 10 = 1
So 75233-43-1 is a valid CAS Registry Number.

, p. 4820 - 4825 (2007/10/02)
A synthetic route to the AB ring system of verrucarol is described.After two routes employing intramolecular cyclization failed, the Diels-Alder reaction of methyl coumalate and isoprene afforded bicyclic lactone 13.Transformation of 13 into hydroxy lacto
