Check Digit Verification of cas no
The CAS Registry Mumber 119490-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,9 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119490-17:
(8*1)+(7*1)+(6*9)+(5*4)+(4*9)+(3*0)+(2*1)+(1*7)=134
134 % 10 = 4
So 119490-17-4 is a valid CAS Registry Number.

Electrophilic nitration of dibenzofuran with nitric acid by a charge-transfer mechanism occurs exclusively at the 3-position and on the other hand, substitution at the 2-position predominates in the acylation, in which a classical ?-complex mechanism is important.
