Check Digit Verification of cas no

The CAS Registry Mumber 1619923-84-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,9,9,2 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1619923-84:
(9*1)+(8*6)+(7*1)+(6*9)+(5*9)+(4*2)+(3*3)+(2*8)+(1*4)=200
200 % 10 = 0
So 1619923-84-0 is a valid CAS Registry Number.

Proline-catalyzed asymmetric Diels-Alder reactions of an o-quinodimethane

Shirakawa, Hidenori,Sano, Hiroshi

supporting information, p. 4095 - 4097 (2014/07/22)

Catalytic asymmetric Diels-Alder reaction of α-amino-o-quinodimethane with α,β-unsaturated aldehydes was achieved with high diastereo- and enantioselectivities in the presence of l-proline, which acts as a promoter to generate the quinodimethane from the corresponding precursor as well as a chiral catalyst for the enantioselective Diels-Alder reaction.
