Check Digit Verification of cas no

The CAS Registry Mumber 156775-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,7,7 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 156775-29:
(8*1)+(7*5)+(6*6)+(5*7)+(4*7)+(3*5)+(2*2)+(1*9)=170
170 % 10 = 0
So 156775-29-0 is a valid CAS Registry Number.

Synthesis, chemical transformation and antimicrobial activity of a novel class of nitroolefins: 1,3-diaryl-2-nitroprop-1-enes

Kodukulla,Trivedi,Vora,Mathur

, p. 819 - 832 (2007/10/02)

The synthesis of novel, biologically active 1,3-diaryl-2- nitroprop-1-enes (4) is reported. The synthesis involves condensation between aromatic aldehydes (1) and β-aryl nitroethanes (3). The chemical transformation of the nitro group in diaryl nitropropenes to a carbonyl function has resulted in a new route to the synthesis of an α-hydroxy analog (7c) of a naturally occurring 3,3',4,4'-tetramethoxy chalcone. The antimicrobial activity of the 1,3-diaryl-2-nitroprop-1-enes (4a- j) was tested against three gram positive bacteria, two gram negative bacteria and two fungi. These compounds exhibited broad spectrum antimicrobial activity.
