451503-17-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 451503-17-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,1,5,0 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 451503-17:
(8*4)+(7*5)+(6*1)+(5*5)+(4*0)+(3*3)+(2*1)+(1*7)=116
116 % 10 = 6
So 451503-17-6 is a valid CAS Registry Number.

Asymmetric synthesis of diarylmethylamines by diastereoselective addition of organometallic reagents to chiral N-tert-butanesulfinimines: Switchover of diastereofacial selectivity

Plobeck, Niklas,Powell, David

, p. 303 - 310 (2007/10/03)

Diastereoselective addition of organometallic reagents to chiral N-tert-butanesulfinimines gave alkylated adducts in high yields and diastereoselectivities. Cleavage of the chiral auxiliary under mildly acidic conditions gave diarylmethylamines in high yi
