Check Digit Verification of cas no
The CAS Registry Mumber 155372-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,7 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 155372-77:
(8*1)+(7*5)+(6*5)+(5*3)+(4*7)+(3*2)+(2*7)+(1*7)=143
143 % 10 = 3
So 155372-77-3 is a valid CAS Registry Number.

A new route for the synthesis of 2-alkanoyl(aryloyl)-5,5-dimethylcyclohexane-1,3-diones as cyclic β-triketones is described. This synthesis was conducted by the reaction of dimedone with cyanogen bromide and triethylamine to form first the intermediate salt, followed by the addition of various aliphatic and aromatic aldehydes. The structures of the products were characterized by IR, 1H, and 13C NMR spectroscopic techniques. A reaction mechanism is proposed.
