Check Digit Verification of cas no
The CAS Registry Mumber 34552-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,5 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34552-16:
(7*3)+(6*4)+(5*5)+(4*5)+(3*2)+(2*1)+(1*6)=104
104 % 10 = 4
So 34552-16-4 is a valid CAS Registry Number.

Synthesis of Halogenated Pyridines via the CuCl-Catalyzed Addition of Polyhaloacetonitriles to Olefins
Pews, R. Garth,Lysenko, Zenon
, p. 5115 - 5119 (2007/10/02)
Halogenated acetonitriles add smoothly to acrolein, methacrolein, and methacrolein dimethyl acetal in the presence of a catalytic amount of CuCl and triphenylphosphine, tri-n-butylphosphine, or triethylamine to give halogenated difunctional adducts.The adducts have been cyclized in high yields under acidic conditions to halogenated pyridines.
