Check Digit Verification of cas no

The CAS Registry Mumber 28168-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,6 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28168-20:
(7*2)+(6*8)+(5*1)+(4*6)+(3*8)+(2*2)+(1*0)=119
119 % 10 = 9
So 28168-20-9 is a valid CAS Registry Number.

Green multicomponent reaction for synthesis of trisubstituted pyrroles in ionic liquid [bmim]BF4

Reddy, G. Narshimha,Likhar, Pravin R.

, p. 6873 - 6879 (2016/08/25)

2,4,5-Trisubstituted pyrrole derivatives were efficiently synthesized by one-pot condensation of 1,3-diones, α-bromoacetophenones, and ammonium acetate in ionic liquid [bmim]BF4. The new synthetic method offers multisubstituted pyrroles with th

Microwave-assisted facile synthesis of trisubstituted pyrrole derivatives

Hanuman Reddy,Mallikarjuna Reddy,Thirupalu Reddy,Rami Reddy

, p. 9805 - 9815 (2015/03/14)

We report efficient synthesis of pyrrole derivatives by use of microwave irradiation. Quantitative yields were obtained in short reaction times. Low yields of product were obtained from alicyclic amino unsaturated ketone derivatives; higher yields were ob
