194021-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194021-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,0,2 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 194021-22:
(8*1)+(7*9)+(6*4)+(5*0)+(4*2)+(3*1)+(2*2)+(1*2)=112
112 % 10 = 2
So 194021-22-2 is a valid CAS Registry Number.

A novel synthetic route to furan-lignans
Wu, Anxin,Wang, Mingyi,Pan, Xinfu
, p. 2087 - 2091 (2007/10/03)
Three naturally occurring furan-lignans and two analogs have been synthesized by a short and efficient route starting from the corresponding aryl acid. The selective reductive removal of allylic hydroxy by palladium oxide in a mixed solvent of THF-CHCl3 was employed as the key step.
