Check Digit Verification of cas no

The CAS Registry Mumber 1245646-49-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,6,4 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1245646-49:
(9*1)+(8*2)+(7*4)+(6*5)+(5*6)+(4*4)+(3*6)+(2*4)+(1*9)=164
164 % 10 = 4
So 1245646-49-4 is a valid CAS Registry Number.

Highly Enantioselective Catalytic Addition of Grignard Reagents to N-Heterocyclic Acceptors

Guo, Yafei,Harutyunyan, Syuzanna R.

, p. 12950 - 12954 (2019/08/07)

General methods to prepare chiral N-heterocyclic molecular scaffolds are greatly sought after because of their significance in medicinal chemistry. Described here is the first general catalytic methodology to access a wide variety of chiral 2- and 4-substituted tetrahydro-quinolones, dihydro-4-pyridones, and piperidones with excellent yields and enantioselectivities, utilizing a single catalyst system.
