Check Digit Verification of cas no

The CAS Registry Mumber 1514927-36-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,4,9,2 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1514927-36:
(9*1)+(8*5)+(7*1)+(6*4)+(5*9)+(4*2)+(3*7)+(2*3)+(1*6)=166
166 % 10 = 6
So 1514927-36-6 is a valid CAS Registry Number.

Regio- and stereospecific synthesis of C-3 functionalized proline derivatives by palladium catalyzed directed C(sp3)-H Arylation

Affron, Dominic P.,Davis, Owen A.,Bull, James A.

, p. 4956 - 4959 (2014)

Functionalization of C(sp3)-H bonds at the unactivated 3-position of proline derivatives has been achieved using aryl iodides and palladium catalysis. This directly affords cis-2,3-disubstituted pyrrolidines as single stereoisomers. 3-Arylation

Cis-fused ring-containing β-lactam the synthetic method of the compound of

-

, (2016/12/01)

The invention discloses a synthetic method of a beta-lactam compound with a cis condensed ring. Substituted or un-substituted pyrrole-2-formic acid, or substituted or un-substituted pyridine-2-formic acid or substituted or un-substituted indole-2-formic acid is used as a starting material, Pd(II) is adopted as a catalyst, and AgOAc or Ag2CO3 is used as an oxidant; a sp3C-H bond at a beta site of an amide substrate 2 (for example Scheme4) is activated through palladium catalysis; a key step of forming a C-N bond in a molecule to successfully construct a beta-lactam framework with the cis condensed ring is generated. According to the synthetic method disclosed by the invention, materials are simple and easily available, the price is cheap, the experiment operation is simple, the route is short and the yield is high; the synthetic method has very high atom economy, a little waste, environment friendliness, a wide scope of application of the substrate and good universality, and can be used for efficiently obtaining the beta-lactam compound with optical activity kept in a chiral manner.
