Check Digit Verification of cas no

The CAS Registry Mumber 1421697-19-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,9 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1421697-19:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*9)+(3*7)+(2*1)+(1*9)=159
159 % 10 = 9
So 1421697-19-9 is a valid CAS Registry Number.

Enantioselective formal aza-Diels-Alder reactions of enones with cyclic imines catalyzed by primary aminothioureas

Lalonde, Mathieu P.,McGowan, Meredeth A.,Rajapaksa, Naomi S.,Jacobsen, Eric N.

supporting information, p. 1891 - 1894 (2013/04/10)

A highly enantio- and diastereoselective synthesis of indolo- and benzoquinolizidine compounds has been developed through the formal aza-Diels-Alder reaction of enones with cyclic imines. This transformation is catalyzed by a new bifunctional primary aminothiourea that achieves simultaneous activation of both the enone and imine reaction components.
