Check Digit Verification of cas no

The CAS Registry Mumber 1703-10-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1703-10:
(6*1)+(5*7)+(4*0)+(3*3)+(2*1)+(1*0)=52
52 % 10 = 2
So 1703-10-2 is a valid CAS Registry Number.

DIRECT AMINATION OF 3(2H)-PYRIDAZINONES: RE-INVESTIGATION OF THE REACTION OF 3,6-DIMETHOXYPYRIDAZINE WITH HYDRAZINE

Coates, William J.,McKillop, Alexander

, p. 1313 - 1329 (2007/10/02)

3,6-Dimethoxypyridazine has been shown to react with hydrazine via 4-amination of 6- methoxy and 6-hydrazino-3(2H)-pyridazinones to give 4-amino-6-methoxy- and 4-amino-6-hydrazino-3(2H)-pyridazinones, and not the corresponding 5-amino isomers as previously reported.The published synthesis of the 5-amino isomers, used to confirm the earlier findings, is incorrect as regards 5-amino-6-hydrazino-3(2H)-pyridazinone, which has been prepared by an alternative route.The 4-aminnation reaction has been extended to 6-chloro-3(2H)-pyridazinone.
