Check Digit Verification of cas no
The CAS Registry Mumber 2161-96-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2161-96:
(6*2)+(5*1)+(4*6)+(3*1)+(2*9)+(1*6)=68
68 % 10 = 8
So 2161-96-8 is a valid CAS Registry Number.

New methods for the synthesis of 4H-dithieno[3,2-b:2′,3′-d]pyrrole

, (2017/08/23)
Various alternative methods for the synthesis of 4H-dithieno[3,2-b:2′,3′-d]pyrrole (DTP) starting from commercially available bromothiophene precursors are presented. Crucial steps involve the Cadogan reaction, Ullmann-type C─N couplings, or Buchwald-Hartwig–type aminations to build up the central pyrrole ring of DTP, respectively. The use of ammonia surrogates afforded the fused target heteroacene in overall yields of 33% to 63%, and the corresponding methods are applicable on large scale.
