Check Digit Verification of cas no
The CAS Registry Mumber 33284-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,8 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33284-43:
(7*3)+(6*3)+(5*2)+(4*8)+(3*4)+(2*4)+(1*3)=104
104 % 10 = 4
So 33284-43-4 is a valid CAS Registry Number.

This work reports the construction of cyclopentene cores from 1,6-enynes and aryl diazo ketones through two new reaction sequences involving initial gold-catalyzed cyclization of 1,6-enynes with diazo species, followed by rhodium-catalyzed skeletal rearrangement of the resulting 3-cyclopropyl-2-en-1-ones. In most instances the rhodium-catalyzed reactions afforded cyclopentene derivatives whereas several n-alkyl- or ortho-substituted phenyl ketones delivered seven-membered oxacycles. A plausible mechanism provides rationales for these two distinct products. (Figure presented.).
