220665-79-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 220665-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,6 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220665-79:
(8*2)+(7*2)+(6*0)+(5*6)+(4*6)+(3*5)+(2*7)+(1*9)=122
122 % 10 = 2
So 220665-79-2 is a valid CAS Registry Number.

Synthesis of phosphoramides for the lewis base-catalyzed allylation and aldol addition reactions

Denmark, Scott E.,Su, Xiping,Nishigaichi, Yutaka,Coe, Diane M.,Wong, Ken-Tsung,Winter, Stephen B. D.,Choi, Jun Young

, p. 1958 - 1967 (2007/10/03)

Both chiral and achiral phosphoramides of diverse structure were prepared from diamines by the coupling to phosphorus(V) or phosphorus(III) reagents. Several enantiopure 1,2-diphenyl-1,2-ethanediamine analogues have been prepared by the reductive coupling of the corresponding N-silylimine with NbCl4(THF)2 and subsequent resolution by the formation of diastereomeric menthyl carbamates. (S,S)-N,N'-Di-(1-naphthyl)-1,2-diphenyl- 1,2-ethanediamine 15 was prepared by the arylation of (S,S)-1,2-diphenyl- 1,2-ethanediamine with naphthyl iodide.
