Check Digit Verification of cas no

The CAS Registry Mumber 1630985-03-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,0,9,8 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1630985-03:
(9*1)+(8*6)+(7*3)+(6*0)+(5*9)+(4*8)+(3*5)+(2*0)+(1*3)=173
173 % 10 = 3
So 1630985-03-3 is a valid CAS Registry Number.

Chiral phosphoric acid-catalyzed enantioselective three- component aza-diels-alder reactions of aminopyrroles and aminopyrazoles

Brioche, Julien,Courant, Thibaut,Alcaraz, Lilian,Stocks, Michael,Furber, Mark,Zhu, Jieping,Masson, Geraldine

supporting information, p. 1719 - 1724 (2014/06/09)

A highly stereoselective three-component Povarov reaction, catalyzed by (R)- and (S)-BINOL hydrogen phosphate, was achieved for the first time with aminopyrroles and aminopyrazoles as 2-azadiene precursors. A variety of aldehydes, enecarbamates, amino-substituted azines participated in the reaction to afford the tetrahydropyrrolopyridines and tetrahydropyrazolopyridines in good yields with excellent diatereo- and enantioselectivities. A stereochemical model is proposed to account for the observed absolute stereochemistry.
