Check Digit Verification of cas no

The CAS Registry Mumber 1287239-89-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,2,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1287239-89:
(9*1)+(8*2)+(7*8)+(6*7)+(5*2)+(4*3)+(3*9)+(2*8)+(1*9)=197
197 % 10 = 7
So 1287239-89-7 is a valid CAS Registry Number.

Formation of N-heterocyclic, donor-stabilized borenium ions

Someya, Chika I.,Inoue, Shigeyoshi,Praesang, Carsten,Irran, Elisabeth,Driess, Matthias

, p. 6599 - 6601 (2011/07/08)

Cationic and zwitterionic boryl bromide species and a borenium-boryl bromide cation have been synthesised which represent new N-donor stabilised cationic boron compounds with β-diketiminate ligands. The unexpected borenium-boryl bromide results from a hea

Comparison of anionic and Lewis acid stabilized N-heterocyclic oxoboranes: Their facile synthesis from a borinic acid

Wang, Yan,Hu, Hongfan,Zhang, Jianying,Cui, Chunming

supporting information; experimental part, p. 2816 - 2819 (2011/06/10)

Have it B=Oth ways: Metal-free anionic oxoboranes and Lewis acid stabilized oxoboranes that feature a formal B-O double bond can be conveniently obtained from an N-heterocyclic borinic acid in the presences of N-heterocyclic carbenes (NHCs) and Lewis acids, respectively (see picture). Copyright
