Check Digit Verification of cas no

The CAS Registry Mumber 66512-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,1 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66512-22:
(7*6)+(6*6)+(5*5)+(4*1)+(3*2)+(2*2)+(1*2)=119
119 % 10 = 9
So 66512-22-9 is a valid CAS Registry Number.

Cu(II)-Mediated N-H and N-Alkyl Aryl Amination and Olefin Aziridination

Munnuri, Sailu,Anugu, Raghunath Reddy,Falck, John R.

supporting information, p. 1926 - 1929 (2019/03/11)

Cu(II)-mediated direct NH2 and NH alkyl aryl aminations and olefin aziridinations are described. These room-temperature, one-pot, environmentally friendly procedures replace costly Rh2 catalysts and, in some instances, display important differences with comparable Rh2- and Fe-supported reactions.

Direct and Stereospecific Synthesis of N-H and N-Alkyl Aziridines from Unactivated Olefins Using Hydroxylamine-O-Sulfonic Acids

Ma, Zhiwei,Zhou, Zhe,Kürti, László

supporting information, p. 9886 - 9890 (2017/08/08)

A RhII-catalyzed direct and stereospecific N-H- and N-alkyl aziridination of olefins is reported that uses hydroxylamine-O-sulfonic acids as inexpensive, readily available, and nitro group-free aminating reagents. Unactivated olefins, featuring a wide range of functional groups, are converted into the corresponding N-H or N-alkyl aziridines in good to excellent yields. This operationally simple, scalable transformation proceeds efficiently at ambient temperature and is tolerant towards oxygen and trace moisture.
