Check Digit Verification of cas no

The CAS Registry Mumber 902453-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,4,5 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 902453-27:
(8*9)+(7*0)+(6*2)+(5*4)+(4*5)+(3*3)+(2*2)+(1*7)=144
144 % 10 = 4
So 902453-27-4 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of α,α,α- trifluoromethylamines by the copper-catalyzed nucleophilic addition of diorganozinc reagents to imines

Lauzon, Caroline,Charette, Andre B.

, p. 2743 - 2745 (2006)

A copper-catalyzed asymmetric addition of diorganozinc reagents to N-phosphinoylimines has been developed for the synthesis of chiral α,α,α-trifluoromethylamines. The trifluoromethyl ketimines, generated in situ from the corresponding hemiaminals, led to
