Check Digit Verification of cas no
The CAS Registry Mumber 33094-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,0,9 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33094-66:
(7*3)+(6*3)+(5*0)+(4*9)+(3*4)+(2*6)+(1*6)=105
105 % 10 = 5
So 33094-66-5 is a valid CAS Registry Number.

Application en serie benzofurannique d'un nouveau procede de nitration par l'acide nitrique en presence de chlorure stannique
Einhorn, Jacques,Demerseman, Pierre,Royer, Rene
, p. 2287 - 2290 (2007/10/02)
A new nitration technique, using nitric acid in the presence of stannic chloride in dichloromethane, has been extended to a series of benzofurans.The ease of performing the reaction as well as the diversity of products that can be obtained under various experimental conditions make it a worthwhile technique.
