139515-84-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139515-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,1 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139515-84:
(8*1)+(7*3)+(6*9)+(5*5)+(4*1)+(3*5)+(2*8)+(1*4)=147
147 % 10 = 7
So 139515-84-7 is a valid CAS Registry Number.

Bis- and Bisarylmethanes: New Molecular Three-Bladed Propellers
Pindur, Ulf,Lomp, Torsten
, p. 927 - 934 (2007/10/02)
Proton-catalyzed arylmethylation of indan and indene derivatives with 4-methoxybenzaldehyde yields novel triarylmethanes bearing indan or indene substituents.According to Mislow's definition, these molecules belong to the class of molecular three-bladed p
