1334482-99-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1334482-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,4,8 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334482-99:
(9*1)+(8*3)+(7*3)+(6*4)+(5*4)+(4*8)+(3*2)+(2*9)+(1*9)=163
163 % 10 = 3
So 1334482-99-3 is a valid CAS Registry Number.

Synthesis of a bicyclic piperazine from l-aspartic acid and application of a fluoride-promoted SNAr coupling

Sieser, Janice E.,Singer, Robert A.,McKinley, Jason D.,Bourassa, Dennis E.,Teixeira, John J.,Long, James

, p. 1328 - 1335 (2012/01/12)

The process development is reported of a pivotal C-N bond formation involving ((7R,9aS)-octahydro-1H-pyrido[1,2-a]pyrazin-7-yl)methanol (2) undergoing nucleophilic aromatic substitution with 3-chlorobenzo[d]isoxazole (3) to furnish ((7R,9aS)-2-(benzo[d]isoxazol-3-yl)octahydro-1H-pyrido[1,2-a] pyrazin-7-yl)methanol (4) as a key intermediate for a family of compounds (1). Essential to the success of the coupling is the use of fluoride in combination with a phase transfer catalyst. The development of an alternative route to bicyclic piperazine 2 that uses l-aspartic acid (20) as a starting material to avoid the need for a classical salt resolution is described.
