Check Digit Verification of cas no

The CAS Registry Mumber 21646-07-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,4 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21646-07:
(7*2)+(6*1)+(5*6)+(4*4)+(3*6)+(2*0)+(1*7)=91
91 % 10 = 1
So 21646-07-1 is a valid CAS Registry Number.

Copper-catalyzed N-N bond formation by homocoupling of ketoximes via n-o bond cleavage: Facile, mild, and efficient synthesis of azines

Zhao, Mi-Na,Liang, Hao,Ren, Zhi-Hui,Guan, Zheng-Hui

experimental part, p. 1501 - 1506 (2012/06/18)

A facile, mild, and efficient copper-catalyzed homocoupling of ketoximes involving N-O bond cleavage in the presence of sodium bisulfite (NaHSO has been developed. This reaction shows good functional group tolerance and affords a broad scope of azines in high yields.
