Check Digit Verification of cas no

The CAS Registry Mumber 115647-98-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,6,4 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115647-98:
(8*1)+(7*1)+(6*5)+(5*6)+(4*4)+(3*7)+(2*9)+(1*8)=138
138 % 10 = 8
So 115647-98-8 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.
