Check Digit Verification of cas no

The CAS Registry Mumber 85429-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,2 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 85429-30:
(7*8)+(6*5)+(5*4)+(4*2)+(3*9)+(2*3)+(1*0)=147
147 % 10 = 7
So 85429-30-7 is a valid CAS Registry Number.

Enamines β-lithiees. I. Preparations et reactions d'alkylation

Duhamel, Lucette,Poirier, Jean-Marie

, p. 297 - 303 (2007/10/02)

The action of alkyllithium reagents on β-bromoenamines 1-9 quickly yields, in THF, β-lithioenamines through halogen - metal exchange.If metallic lithium is used instead of organolithium compounds, β-lithioenamines are also formed but in this case they are accompanied by small amounts of by-products.The action of alkyllithium reagents R1Li on the β-chloroenamine 10 provides a new source of β-lithioenamines in which nucleophilic insertion of the R1 group takes place. β-Lithioenamines are stable compounds even up to 20 deg C in most cases.With alkyl iodides, β-lithioenamines react vigorously even at low temperature.The reaction is stereospecific with retention of configuration.This reaction generates either β-substituted enamines or, by easy acidic hydrolysis, α-substituted carbonyl compounds.The C-alkylation reaction is observed alone.
