81451-21-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81451-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,5 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81451-21:
(7*8)+(6*1)+(5*4)+(4*5)+(3*1)+(2*2)+(1*1)=110
110 % 10 = 0
So 81451-21-0 is a valid CAS Registry Number.

Reactions with Heterocyclic β-Enaminoesters: A Novel Synthesis of 2-Amino-3-ethoxycarbonyl-(4H)-pyrans

Elmoghayer, Mohamed Rifaat Hamza,Khalifa, Mohamed Ali Elsayed,Ibraheim, Mohamed Kamal Ahmed,Elnagdi, Mohamed Hilmy

, p. 53 - 58 (1982)

The reaction of ethyl cyanoacetate with α-cyanochalcone (1) leads to the formation of β-enaminoesters (3) via Michael addition.Compound 3 reacts with phenylmagnesium bromide to give the β-enaminoketone 5.Acetylation of 3 gives the acetyl product 4.Each of compounds 1 and 3 reacts with malononitrile to give β-enaminonitrile 6.Phenylhydrazine reacts with 3 to give the hydrazone 7.Similarly 3-phenyl-5-aminopyrazole reacts with 3 to give the Schiff base 8. - Keywords: Enaminopyrans; Michael addition; Pyrans, cleavage of
