139413-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139413-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139413-83:
(8*1)+(7*3)+(6*9)+(5*4)+(4*1)+(3*3)+(2*8)+(1*3)=135
135 % 10 = 5
So 139413-83-5 is a valid CAS Registry Number.

Efficient synthesis of N-allylated 2-nitroiminoimidazolidine analogues from Baylis–Hillman bromides

Kumar, Sriramoju Bharath,Pavan Kumar, Chebolu Naga Sesha Sai,Santhoshi, Amlipur,Kumar, Koochana Pranay,Murthy,Jayathirtha Rao, Vaidya

, p. 131 - 136 (2017/01/11)

Various Baylis–Hillman–derived new N-allylated 2-nitroiminoimidazolidine analogs were efficiently prepared using potassium carbonate as base. Simple workup procedure, excellent yields, and mild reaction conditions are the salient features of this method. All the synthesized compounds are screened for their larvicidal activity on fourth instar mosquito larvae, Culex quinquefasciatus.

Mild and practical stereoselective synthesis of (Z)- and (E)-allyl bromides from Baylis-Hillman adducts using Appel agents (PPh3/CBr4): a facile synthesis of semiplenamides C and E

Das, Biswanath,Damodar, Kongara,Bhunia, Nisith,Shashikanth, Boddu

supporting information; experimental part, p. 2072 - 2074 (2009/09/05)

Appel agents (PPh3/CBr4) have been utilized for high-yielding stereoselective synthesis of (Z)- and (E)-allyl bromides from Baylis-Hillman adducts at room temperature. The method has been applied for the synthesis of naturally occurr
