Check Digit Verification of cas no

The CAS Registry Mumber 32293-59-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,9 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 32293-59:
(7*3)+(6*2)+(5*2)+(4*9)+(3*3)+(2*5)+(1*9)=107
107 % 10 = 7
So 32293-59-7 is a valid CAS Registry Number.

Reduction of hydrazines to amines with aqueous solution of titanium(iii) trichloride

Zhang, Yan,Tang, Qiang,Luo, Meiming

supporting information; experimental part, p. 4977 - 4982 (2011/08/05)

N-N bond cleavage in hydrazines is widely used in the preparation of amines and thus occupies a significant place in organic synthesis. In this paper, we report a new method for the reductive cleavage of N-N bonds in hydrazines by commercially available and cheap aqueous titanium(iii) trichloride. The reaction proceeds smoothly under a broad pH range from acidic to neutral and basic conditions to afford amines in good yields. This method is compatible with substrates containing functionalities such as C-C double bonds, benzyl-nitrogen bonds, benzyloxy and acyl groups. The Royal Society of Chemistry 2011.
