1026892-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1026892-45-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,8,9 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1026892-45:
(9*1)+(8*0)+(7*2)+(6*6)+(5*8)+(4*9)+(3*2)+(2*4)+(1*5)=154
154 % 10 = 4
So 1026892-45-4 is a valid CAS Registry Number.

Synthesis of magnoshinin and cyclogalgravin: Modified stobbe condensation reaction
Yvon,Datta,Le,Charlton
, p. 1556 - 1560 (2007/10/03)
The development of new methods for lignan synthesis is reported. A recently reported method for the preparation of 1-aryl-1,2-dihydronaphthalenes is exploited to prepare magnoshinin, a naturally occurring lignan, and cyclogalgravin (3,4-dehydrogalbulin), a derivative of a natural lignan.
