Check Digit Verification of cas no

The CAS Registry Mumber 443923-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,9,2 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 443923-79:
(8*4)+(7*4)+(6*3)+(5*9)+(4*2)+(3*3)+(2*7)+(1*9)=163
163 % 10 = 3
So 443923-79-3 is a valid CAS Registry Number.

First synthesis of (+)-rengyolone and (+)- and (-)-menisdaurilide

Canto, Mariona,De March, Pedro,Figueredo, Marta,Font, Josep,Rodriguez, Sonia,Alvarez-Larena, Angel,Piniella, Juan F.

, p. 455 - 459 (2002)

The benzofuranone natural products (+)-rengyolone and (+)- and (-)-menisdaurilide have been synthesised for the first time from a common enantiopure cyclohexane building block derived from a monoketal of p-benzoquinone.

From p-benzoquinone to cyclohexane chirons: First asymmetric synthesis of (+)-rengyolone and (+)- and (-)-menisdaurilide

Busque, Felix,Canto, Mariona,De March, Pedro,Figueredo, Marta,Font, Josep,Rodriguez, Sonia

, p. 2021 - 2032 (2007/10/03)

Starting from a common, easily available, enantiopure monoketal of p-benzoquinone, the synthesis of a large number of cyclohexane chirons has been achieved. The first synthesis of (+)-rengyolone and (+)- and (-)-menisdaurilide has been performed from one of these new building blocks. The wide variety of functional groups of this series of chirons makes them useful for subsequent synthetic processes.
