Check Digit Verification of cas no

The CAS Registry Mumber 79225-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,2 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79225-59:
(7*7)+(6*9)+(5*2)+(4*2)+(3*5)+(2*5)+(1*9)=155
155 % 10 = 5
So 79225-59-5 is a valid CAS Registry Number.

Action of Grignard Reagents on 6-Arylpyridazin-3(2H)-thiones

Ismail, M. Fekry,Kaddah, A. M.,Elkafrawy, A. F.,Sayed, Fekria S.,El-Sawy, O. M.

, p. 415 - 420 (2007/10/02)

6-Arylpyridazin-3(2H)-thiones (1a-c) react with Grignard reagents by 1,4-addition to give either 4-substituted 6-aryl-4,5-dihydropyridazin-3(2H)-thiones (2a-c) or their dehydrogenated products, namely 4-substituted 6-arylpyridazin-3(2H)-thiones (3d-k).The

Reactions of Grignard Reagents with 4-Cyano-5,6-diphenyl and -6-p-Tolyl-3(2H)-pyridazinones and 6-p-Tolyl-3(2H)-pyridazinethione

Jahine, H.,Zaher, H. A.,Sherif, O.,Seada, M.

, p. 502 - 503 (2007/10/02)

4-Cyano-5,6-diphenyl-3(2H)-pyridazinone (I) reacts with phenylmagnesium bromide to give 4-benzoyl-4,5,6-triphenyl-4,5-dihydro-3(2H)-pyridazinone (II) and 4,5,6-triphenyl-3(2H)-pyridazinone (III).Reaction of 6-p-tolyl-3(2H)-pyridazinone (IV) with phenylmagnesium bromide in THF-ether gives 5-phenyl-6-p-tolyl-4,5-dihydro-3(2H)-pyridazinone (V) and with arylmagnesium bromides in benzene affords 4-aryl-6-tolyl-3(2H)-pyridazinones (IVb-d). 6-p-Tolyl-3(2H)-pyridazinethione (VIa) reacts with arylmagnesium bromides in benzene or THF-ether to give 4-aryl-6-p-tolyl-3(2H)-pyridazinethiones (VIb,c).
