1169983-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1169983-13-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,9,8 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1169983-13:
(9*1)+(8*1)+(7*6)+(6*9)+(5*9)+(4*8)+(3*3)+(2*1)+(1*3)=204
204 % 10 = 4
So 1169983-13-4 is a valid CAS Registry Number.

Development of chiral metal amides as highly reactive catalysts for asymmetric [3 + 2] cycloadditions

Yamashita, Yasuhiro,Yoshimoto, Susumu,Dutton, Mark J.,Kobayashi, Sh?

, p. 1447 - 1452 (2016/08/02)

Highly efficient catalytic asymmetric [3 + 2] cycloadditions using a chiral copper amide are reported. Compared with the chiral CuOTf/Et3 N system, the CuHMDS system showed higher reactivity, and the desired reactions proceeded in high yields a

Highly enantioselective 1,3-dipolar cycloaddition of azomethine ylides catalyzed by AgOAc/TF-BiphamPhos

Wang, Chun-Jiang,Xue, Zhi-Yong,Liang, Gang,Lu, Zhou

supporting information; experimental part, p. 2905 - 2907 (2009/12/01)

A novel and highly efficient AgOAc/TF-BiphamPhos catalytic system shows excellent reactivity, diastereo-/enantioselectivity and structural scope in asymmetric 1,3-dipolar cycloaddition of azomethine ylides, especially derived from various α-substituted α-amino acids, with N-substituted maleimides and other electron-deficient alkenes.
