Check Digit Verification of cas no

The CAS Registry Mumber 1262613-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,6,1 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1262613-52:
(9*1)+(8*2)+(7*6)+(6*2)+(5*6)+(4*1)+(3*3)+(2*5)+(1*2)=134
134 % 10 = 4
So 1262613-52-4 is a valid CAS Registry Number.

Efficient synthesis of nebularine and vidarabine via dehydrazination of (hetero)aromatics catalyzed by CuSO4 in water

Xia, Ran,Xie, Ming-Sheng,Niu, Hong-Ying,Qu, Gui-Rong,Guo, Hai-Ming

supporting information, p. 1077 - 1081 (2014/03/21)

A simple dehydrazination reaction has been achieved in the presence of a catalytic amount of CuSO4 for the first time. With CuSO4 (2 mol%) as a catalyst and water as a solvent, the dehydrazination products were obtained in good yields (66-95%). Moreover, the drugs nebularine and vidarabine were afforded successfully, and vidarabine could be produced on a 0.923 kg scale, which shows good potential for industrial applications.
