205108-17-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 205108-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,1,0 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 205108-17:
(8*2)+(7*0)+(6*5)+(5*1)+(4*0)+(3*8)+(2*1)+(1*7)=84
84 % 10 = 4
So 205108-17-4 is a valid CAS Registry Number.

Enantioselective, Stereodivergent Hydroazidation and Hydroamination of Allenes Catalyzed by Acyclic Diaminocarbene (ADC) Gold(I) Complexes

Khrakovsky, Dimitri A.,Tao, Chuanzhou,Johnson, Miles W.,Thornbury, Richard T.,Shevick, Sophia L.,Toste, F. Dean

supporting information, p. 6079 - 6083 (2016/05/19)

The gold-catalyzed enantioselective hydroazidation and hydroamination reactions of allenes are presented herein. ADC gold(I) catalysts derived from BINAM were critical for achieving high levels of enantioselectivity in both transformations. The sense of enantioinduction is reversed for the two different nucleophiles, allowing access to both enantiomers of the corresponding allylic amines using the same catalyst enantiomer. Chiral allylic azides and amines are obtained by enantioselective hydroazidation and hydroamination of allenes catalyzed by acyclic diaminocarbene gold(I) catalysts derived from BINAM. The sense of enantioinduction is reversed for the two different nucleophiles, allowing easy access to both enantiomers with a single catalyst enantiomer.
