Check Digit Verification of cas no
The CAS Registry Mumber 77331-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,3 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77331-28:
(7*7)+(6*7)+(5*3)+(4*3)+(3*1)+(2*2)+(1*8)=133
133 % 10 = 3
So 77331-28-3 is a valid CAS Registry Number.

STABLE CARBON-YLIDES
Doleschall, Gabor,Seres, Peter
, p. 209 - 216 (2007/10/02)
5-Acylmethylene-1,2,4-triazolium salts were synthesized and converted to stable anhydrobases by aqueous alkali.The close analogy of their spectra with those of phosphorus-ylides and their reactions suggest that the anhydrobases may be regarded as carbon-ylides. α,β-Unsaturated aldehydes were synthesized in moderate yield by selective reduction of the salts folloved by acid hydrolysis.
