Check Digit Verification of cas no
The CAS Registry Mumber 156570-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,7 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156570-11:
(8*1)+(7*5)+(6*6)+(5*5)+(4*7)+(3*0)+(2*1)+(1*1)=135
135 % 10 = 5
So 156570-11-5 is a valid CAS Registry Number.

Synthetic applications of fluorinated phenyllithiums: Preparation of fluorinated α-methylstyrenes, benzhydrols, benzophenones and aryltrimethylsilanes
Yarwood, Thomas David,Waring, Anthony John,Coe, Paul Leslie
, p. 113 - 119 (1996)
Regioselective preparations of a number of fluorinated phenyllithiums have recently been reported, which in some cases also contain one or more bromine substituents. These have now been applied to the synthesis of the corresponding halogenated 2-arylpropenes (α-methyl-styrenes), benzhydrols, trifluoromethylbenzhydrols, benzophenones and aryltrimethylsilanes.
