Check Digit Verification of cas no

The CAS Registry Mumber 1345669-64-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,6,6 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1345669-64:
(9*1)+(8*3)+(7*4)+(6*5)+(5*6)+(4*6)+(3*9)+(2*6)+(1*4)=188
188 % 10 = 8
So 1345669-64-8 is a valid CAS Registry Number.

Ultrasound promoted the synthesis of N-propargylic β-enaminones

Martins, Marcos A.P.,Rossatto, Marcelo,Prola, Liziê D.T.,Pizzuti, Lucas,Moreira, Dayse N.,Campos, Patrick T.,Frizzo, Clarissa P.,Zanatta, Nilo,Bonacorso, Helio G.

, p. 227 - 231 (2012/04/10)

The synthesis of 14 novel N-propargylic β-enaminones from the reaction of β-alkoxy vinyltrihalomethyl[carboxyethyl] ketones [R 3C(O)CHC(R1)OMe, where R3 = CF3, CCl3, CO2Et and R1 = Me, Et, Pr, Bu, i-Pent, CH2CH2CO2Me] with propargyl amines [R 2NHCH2CCH, where R2 = Pr, PhCH2] is reported. Yields, solvents and reaction times needed for reaction completion, by microwave irradiation (MW), conventional thermal heating (TH) and under ultrasound irradiation (US) are compared. The best results were obtained under US irradiation in good to excellent yields (70-93%).
