The CAS Registry Mumber 30951-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,5 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30951-74:
(7*3)+(6*0)+(5*9)+(4*5)+(3*1)+(2*7)+(1*4)=107
107 % 10 = 7
So 30951-74-7 is a valid CAS Registry Number.

Construction of nitrogen-heterocyclic compounds through zirconium mediated intramolecular alkene-carbonyl coupling reaction of N-(o-alkenylaryl)carbamate derivatives

Takigawa, Yasushi,Ito, Hisanaka,Omodera, Katsunori,Ito, Maiko,Taguchi, Takeo

, p. 1385 - 1392 (2007/10/03)

Intramolecular alkene-carbonyl coupling reaction of N-benzyl-N-(o- alkenylaryl)carbamate derivative derived from o-aminostyrene, o-(aminomethyl)styrene and o-aminoallylbenzene smoothly proceeded by treating with zirconocene-butene complex to give the corresponding lactam derivative.
