Check Digit Verification of cas no
The CAS Registry Mumber 1568-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1568-74:
(6*1)+(5*5)+(4*6)+(3*8)+(2*7)+(1*4)=97
97 % 10 = 7
So 1568-74-7 is a valid CAS Registry Number.

Metal-free and solvent-free synthesis of: M -terphenyls through tandem cyclocondensation of aryl methyl ketones with triethyl orthoformate

, p. 12113 - 12118 (2020)
Reported here is a novel cyclocondensation of aryl methyl ketones and triethyl orthoformate for the simple synthesis of m-terphenyls. In the presence of a catalytic amount of TfOH, alkyl- and chloro-substituted acetophenones produced a series of terphenyls through a tandem reaction which merged six steps into a one-pot procedure. Moreover, the corresponding ester products were obtained when using other substituted acetophenones as the starting materials under the same reaction conditions.
