494844-69-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 494844-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,8,4 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 494844-69:
(8*4)+(7*9)+(6*4)+(5*8)+(4*4)+(3*4)+(2*6)+(1*9)=208
208 % 10 = 8
So 494844-69-8 is a valid CAS Registry Number.

A new convergent approach to α-branched alkynes

Renard, Delphine,Rezaei, Hadi,Zard, Samir Z.

, p. 1257 - 1260 (2002)

A variety of α-branched alkynes can be easily assembled by a Knoevenagel type condensation of 4-unsubstituted isoxazolin-5-ones with aldehydes or ketones, followed by conjugate addition of an organometallic reagent and nitrosative cleavage of the heterocy
