827-68-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 827-68-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 827-68:
(5*8)+(4*2)+(3*7)+(2*6)+(1*8)=89
89 % 10 = 9
So 827-68-9 is a valid CAS Registry Number.

Preparation and decarboxylative rearrangement of (Z)-enyne esters

Woo, Jacqueline C.S.,Walker, Shawn D.,Faul, Margaret M.

, p. 5679 - 5682 (2008/02/10)

A method to assemble (Z)-enyne esters via palladium-catalyzed cross coupling reactions of enol tosylates is reported. A base-mediated one-pot decarboxylative rearrangement of the enynes to enones is described. The scope of this process is examined.
