1221740-56-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1221740-56-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,7,4 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1221740-56:
(9*1)+(8*2)+(7*2)+(6*1)+(5*7)+(4*4)+(3*0)+(2*5)+(1*6)=112
112 % 10 = 2
So 1221740-56-2 is a valid CAS Registry Number.

Chiral N-phosphonyl imine chemistry: An efficient asymmetric synthesis of chiral N-phosphonyl propargylamines

Kaur, Parminder,Shakya, Gaurav,Sun, Hao,Pan, Yi,Li, Guigen

, p. 1091 - 1096 (2010)

A variety of substituted chiral propargylamines have been synthesized by reacting chiral N-phosphonylimines with lithium aryl/alkyl acetylides. Seventeen examples were studied to give excellent yields (>90%) and diastereoselectivities (96:4 to 99:1). It was found that the types of bases for generating acetylides and solvents are crucial for effectiveness of this asymmetric reaction. In addition, N,N-isopropyl group on chiral N-phosphonylimine auxiliary was proven to be superior to other protecting groups in controlling diastereoselectivity. The Royal Society of Chemistry.
