Check Digit Verification of cas no

The CAS Registry Mumber 342623-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,6,2 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 342623-56:
(8*3)+(7*4)+(6*2)+(5*6)+(4*2)+(3*3)+(2*5)+(1*6)=127
127 % 10 = 7
So 342623-56-7 is a valid CAS Registry Number.

Highly efficient and practical phosphoramidite-copper catalysts for amination of aryl iodides and heteroaryl bromides with alkylamines and N(H)-heterocycles

Zhang, Zhanjin,Mao, Jincheng,Zhu, Di,Wu, Fan,Chen, Huilin,Wan, Boshun

, p. 4435 - 4443 (2007/10/03)

A highly efficient copper-catalyzed system using phosphoramidite as ligands was applied to N-arylation of alkylamines and N(H)-heterocycles with aryl iodides and heteroaryl bromides. The reactions were carried out in relative mild conditions and good to excellent yields were obtained.
