Check Digit Verification of cas no

The CAS Registry Mumber 128534-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128534-71:
(8*1)+(7*2)+(6*8)+(5*5)+(4*3)+(3*4)+(2*7)+(1*1)=134
134 % 10 = 4
So 128534-71-4 is a valid CAS Registry Number.

α-IODO-β-NITROSTILBENE IN THE REACTION WITH MORPHOLINE AND PIPERIDINE

Todres, Z. V.,Ermekov, D. S.

, p. 957 - 959 (1992)

The reaction of α-iodo-β-nitrostilbene with morpholine or piperidine yields α-nitro-β-morpholino- or α-nitro-β-piperidinostilbene. The reaction is regioselective and stereospecific: only the iodine, and not the nitro group, is substituted; the product obt

Reactions of 2-Arylthio-and 2-Arylsulfonyl-1-nitro-1-phenylethenes with Amines

Kuz'mina,Lipina,Kropotova,Berkova,Pavlova

, p. 82 - 86 (2007/10/03)

2-Arylthio- and 2-arylsulfonyl-1-nitro-1-phenylethenes react with amines to give the corresponding nitroenamines whose configuration (E or Z) depends on the amine structure. Primary amines gives rise to Z-nitroenamines, secondary cyclic amines with 2-aryl

Stereochemistry in nucleophilic vinylic substitution of activated nitro olefins

Park, Kyong Pae,Ha, Hyun-Joon

, p. 3006 - 3009 (2007/10/02)

Each of E- and Z-isomers of activated α,β-dinitro olefins and α-iodo-β-nitrostilbene reacted ith several different types of nucleophiles such as amines, thiocyanate, and p-toluenethiolate. Only Z-isomers of vinylicsubstituted olefins with amines and thioc
