Check Digit Verification of cas no

The CAS Registry Mumber 334685-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,6,8 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 334685-48:
(8*3)+(7*3)+(6*4)+(5*6)+(4*8)+(3*5)+(2*4)+(1*8)=162
162 % 10 = 2
So 334685-48-2 is a valid CAS Registry Number.

Halogen-containing pyridines. 7. Synthesis and some conversions of (3,5-dichloro-2-pyridyl)hydrazine

Kobrakov,Korolev,Rybina,Kelarev

, p. 931 - 943 (2000)

(3,5-Dichloro-2-pyridyl)hydrazine was synthesized by the interaction of 2,3,5-trichloropyridine with hydrazine hydrate. Reaction of the former with carbonyl compounds gave N-(3,5-dichloro-2-pyridyl)hydrazones, and with acid anhydrides N′-acyl derivatives were formed. Azodyestuffs containing 3,5-dichloropyridyl fragments were obtained from some of the hydrazones synthesized.
