Check Digit Verification of cas no

The CAS Registry Mumber 39220-97-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,2 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39220-97:
(7*3)+(6*9)+(5*2)+(4*2)+(3*0)+(2*9)+(1*7)=118
118 % 10 = 8
So 39220-97-8 is a valid CAS Registry Number.

One-pot solid phase synthesis of (E)-nitroalkenes

Rokhum, Lalthazuala,Bez, Ghanashyam

, p. 5500 - 5504 (2013/09/23)

An efficient one-pot protocol for the synthesis of (E)-nitroalkenes by reaction of aldehydes and nitroalkanes in the presence of polymer-bound triphenylphosphine, iodine and imidazole is described. Although the reaction works with similar efficiency with triphenylphosphine and its polymer-bound version, easy removal of the unwanted polymer-bound triphenylphosphine oxide and its recovery as triphenylphosphine provide the edge for practical application of the method.
