Check Digit Verification of cas no

The CAS Registry Mumber 299204-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,9,2,0 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 299204-41:
(8*2)+(7*9)+(6*9)+(5*2)+(4*0)+(3*4)+(2*4)+(1*1)=164
164 % 10 = 4
So 299204-41-4 is a valid CAS Registry Number.

Rhodium(II)-catalyzed equilibration of push-pull carbonyl and ammonium ylides. A computationally based understanding of the reaction pathway

Padwa, Albert,Snyder, James P.,Curtis, Erin A.,Sheehan, Scott M.,Worsencroft, Kimberly J.,Kappe, C. Oliver

, p. 8155 - 8167 (2007/10/03)

Δ-Diazo esters containing an amido group in the γ-position have been found to undergo a rhodium(II)-catalyzed transformation, producing five-membered ammonium or carbonyl ylides depending on the reaction conditions used. In the absence of an external dipo
