27843-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27843-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,4 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27843-14:
(7*2)+(6*7)+(5*8)+(4*4)+(3*3)+(2*1)+(1*4)=127
127 % 10 = 7
So 27843-14-7 is a valid CAS Registry Number.

Preparation of Tertiary Amines from Tris(2-cyanoethyl)amine Using Three Successive Cobalt-Catalyzed Electrophilic Aminations with Organozinc Halides

Gra?l, Simon,Knochel, Paul

, (2020/03/03)

We report a stepwise preparation of triple alkylated or arylated tertiary amines, starting from commercially available tris(2-cyanoethyl)amine using three successive reaction sequences involving a selective oxidation (formation of an N-oxide followed by a

Microwave-assisted, rapid, solvent-free aza-michael reaction by perchloric acid impregnated on silica gel

Singh, Surya Prakash,Kumar, T. Vijaya,Chandrasekharam,Giribabu,Reddy, P. Yella

experimental part, p. 3982 - 3989 (2009/12/24)

Highly efficient solvent-free aza-Michael additions of a variety of amines to,-unsaturated carbonyl compounds under microwave-irradiation conditions catalyzed by perchloric acid impregnated on silica gel (HClO4/SiO2) is reported. The reactions are completed within 2-7min in a microwave oven to produce the corresponding adducts in excellent yields, and the catalyst can be recovered and reused.
