The CAS Registry Mumber 143365-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143365-99:
(8*1)+(7*4)+(6*3)+(5*3)+(4*6)+(3*5)+(2*9)+(1*9)=135
135 % 10 = 5
So 143365-99-5 is a valid CAS Registry Number.

A convenient synthesis of protected E-enynals via cross-coupling of vinyltin acetals with bromoalkynes

Beaudet,Parrain,Quintard

, p. 3647 - 3650 (2007/10/02)

E-conjugated enynes bearing an acetal function on the allylic or the homoallylic position or/and on the propargylic or the homopropargylic position were conveniently obtained at room temperature in DMF via cross-coupling of the corresponding vinyltins with 1-bromoalk-1-ynes in the presence of Pd(II) catalysts.
