Check Digit Verification of cas no

The CAS Registry Mumber 20799-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,9 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20799-61:
(7*2)+(6*0)+(5*7)+(4*9)+(3*9)+(2*6)+(1*1)=125
125 % 10 = 5
So 20799-61-5 is a valid CAS Registry Number.

Synergistic Catalysis of Ionic Br?nsted Acid and Photosensitizer for a Redox Neutral Asymmetric α-Coupling of N-Arylaminomethanes with Aldimines

Uraguchi, Daisuke,Kinoshita, Natsuko,Kizu, Tomohito,Ooi, Takashi

, p. 13768 - 13771 (2015)

A redox neutral, highly enantioselective coupling between N-arylaminomethanes and N-sulfonyl aldimines was developed by harnessing the efficient catalysis of P-spiro chiral arylaminophosphonium barfate and a transition-metal photosensitizer under visible
