Calculate Digit Verification of CAS Registry Number 1031281-75:
(9*1)+(8*0)+(7*3)+(6*1)+(5*2)+(4*8)+(3*1)+(2*7)+(1*5)=100
100 % 10 = 0
So 1031281-75-0 is a valid CAS Registry Number.

New regiocontrolled synthesis of functionalized pyrroles from 2-azetidinone-tethered allenols

Alcaide, Benito,Almendros, Pedro,Carrascosa, Rocio,Redondo, Maria C.

, p. 637 - 643 (2008/12/21)

A new one-pot approach to synthesize densely substituted racemic and enantiopure pyrroles from β-lactams has been developed. The approach relies on the regiocontrolled cyclization of β-allenamine intermediates derived from the ring opening of 2-azetidinon
