69950-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69950-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,5 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69950-70:
(7*6)+(6*9)+(5*9)+(4*5)+(3*0)+(2*7)+(1*0)=175
175 % 10 = 5
So 69950-70-5 is a valid CAS Registry Number.

Nitration of some 3-(2-furyl)-2-propenones with dinitrogen tetraoxide
Sitkin,Klimenko
, p. 423 - 428 (2007/10/03)
Nitration of 3-(2-furyl)-2-propenones with dinitrogen tetraoxide leads to the corresponding 3-(4-nitro-2-furyl)-2-propenones. If the furyl group contains a substituent in position 5, the nitration occurs at the side chain to afford 3-(5-R-2-furyl)-2-nitro
