Check Digit Verification of cas no

The CAS Registry Mumber 1094281-95-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,4,2,8 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1094281-95:
(9*1)+(8*0)+(7*9)+(6*4)+(5*2)+(4*8)+(3*1)+(2*9)+(1*5)=164
164 % 10 = 4
So 1094281-95-4 is a valid CAS Registry Number.

Palladium-catalysed direct regioselective C5-arylation of a thiophene bearing a cyclopropyl ketone group at C2

Beladhria, Anissa,Gottumukkala, Aditya L.,Youssef, Chiraz,Bheeter, Charles Beromeo,Ben Ammar, Hamed,Ben Salem, Ridha,Doucet, Henri

, p. 119 - 122 (2013/09/02)

A thiophene bearing a cyclopropyl ketone group at C2 was successfully employed in palladium-catalysed direct arylation. The reaction proceeds regioselectively at C5 without decomposition of the cyclopropyl ketone substituent. These couplings were performed employing as little as 0.5 mol% of ligand-free Pd(OAc)2 catalyst with electron-deficient aryl bromides. A wide variety of functional groups on the aryl bromide such as nitrile, nitro, acetyl, formyl, benzoyl, ester, trifluoromethyl, fluoro or methoxy was tolerated. 2013 Elsevier Science.
