Check Digit Verification of cas no

The CAS Registry Mumber 1402909-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,9,0 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1402909-83:
(9*1)+(8*4)+(7*0)+(6*2)+(5*9)+(4*0)+(3*9)+(2*8)+(1*3)=144
144 % 10 = 4
So 1402909-83-4 is a valid CAS Registry Number.

Catalytic asymmetric [4+2] annulation initiated by an aza-rauhut-currier reaction: Facile entry to highly functionalized tetrahydropyridines

Shi, Zugui,Yu, Peiyuan,Loh, Teck-Peng,Zhong, Guofu

, p. 7825 - 7829 (2012/09/08)

Under control: The first example of chiral amino phosphine catalysts for the title reaction between vinyl ketones and N-sulfonyl-1-aza-1,3-dienes has been developed. Under ambient conditions, this protocol provides straightforward access to densely functionalized, enantioenriched tetrahydropyridines with high levels of sterecontrol in good to excellent yields.
