Check Digit Verification of cas no

The CAS Registry Mumber 53884-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,8,8 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53884-34:
(7*5)+(6*3)+(5*8)+(4*8)+(3*4)+(2*3)+(1*4)=147
147 % 10 = 7
So 53884-34-7 is a valid CAS Registry Number.

Practical Singly and Doubly Electrophilic Aminating Agents: A New, More Sustainable Platform for Carbon-Nitrogen Bond Formation

Kattamuri, Padmanabha V.,Yin, Jun,Siriwongsup, Surached,Kwon, Doo-Hyun,Ess, Daniel H.,Li, Qun,Li, Guigen,Yousufuddin, Muhammed,Richardson, Paul F.,Sutton, Scott C.,Kürti, László

Given the importance of amines in a large number of biologically active natural products, active pharmaceutical ingredients, agrochemicals, and functional materials, the development of efficient C-N bond-forming methods with wide substrate scope continues to be at the frontier of research in synthetic organic chemistry. Here, we present a general and fundamentally new synthetic approach for the direct, transition-metal-free preparation of symmetrical and unsymmetrical diaryl-, arylalkyl-, and dialkylamines that relies on the facile single or double addition of readily available C-nucleophiles to the nitrogen atom of bench-stable electrophilic aminating agents. Practical single and double polarity reversal (i.e., umpolung) of the nitrogen atom is achieved using sterically and electronically tunable ketomalonate-derived imines and oximes. Overall, this novel approach represents an operationally simple, scalable, and environmentally friendly alternative to transition-metal-catalyzed C-N cross-coupling methods that are currently used to access structurally diverse secondary amines.
