Check Digit Verification of cas no
The CAS Registry Mumber 13142-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13142-57:
(7*1)+(6*3)+(5*1)+(4*4)+(3*2)+(2*5)+(1*7)=69
69 % 10 = 9
So 13142-57-9 is a valid CAS Registry Number.

Transition Metal-Free Carbazole Synthesis from Arylureas and Cyclohexanones

An efficient strategy for carbazole synthesis from arylureas and cyclohexanones under transition metal-free conditions has been developed. The combined use of potassium iodide and iodine could significantly improve the reaction efficiency to provide 2,6-disubstituted 9-arylcarbazoles in moderate to good yields. In this kind of transformation, the whole carbazole moiety (except the nitrogen atom) comes from two equivalents of cyclohexanones. (Figure presented.).
