Check Digit Verification of cas no
The CAS Registry Mumber 84540-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,4 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84540-37:
(7*8)+(6*4)+(5*5)+(4*4)+(3*0)+(2*3)+(1*7)=134
134 % 10 = 4
So 84540-37-4 is a valid CAS Registry Number.

Synthesis of Mesogenic Compounds, Catalyzed by Metal Complexes. II. A New Method of Synthesis of 4,4'-Dialkylbiphenyls
Bumagin, N. A.,Luzikova, E. V.,Beletskaya, I. P.
, p. 1487 - 1491 (2007/10/03)
A new method for the synthesis of 4,4'-dialkylbiphenyls containing both n-alkyl- and 4-trans-n-alkylcyclohexyl substituents, based on highly selective reactions of monoalkylation and monoacylation of 1,4-dibromobenzene in the presence of palladium complexes is developed.
