156769-16-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156769-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,7,6 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156769-16:
(8*1)+(7*5)+(6*6)+(5*7)+(4*6)+(3*9)+(2*1)+(1*6)=173
173 % 10 = 3
So 156769-16-3 is a valid CAS Registry Number.

Ruthenium dioxide in fluoro acid medium V. Application to the non phenolic oxidative coupling of diarylbutanes. Conformational studies of cis and trans deoxyschizandrins

Dhal,Landais,Lebrun,Lenain,Robin

, p. 1153 - 1164 (2007/10/02)

Ruthenium (IV) dioxide dihydrate in fluoro acidic medium was found to be a very efficient agent for the non phenolic oxidative coupling of diarylbutanes. We observed along with the expected aryl-aryl coupling, an unusual aryl-benzyl coupling, leading to a known class of lignans, the aryltetralins. Conformational studies of resultant cis and trans deoxyschizandrins were performed using high resolution NMR and molecular models.
