1067645-72-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1067645-72-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,7,6,4 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1067645-72:
(9*1)+(8*0)+(7*6)+(6*7)+(5*6)+(4*4)+(3*5)+(2*7)+(1*2)=170
170 % 10 = 0
So 1067645-72-0 is a valid CAS Registry Number.

Copper-catalyzed mild and efficient entry to 1-substituted indazolones
Tanimori, Shinji,Ozaki, Yuka,Iesaki, Yasukazu,Kirihata, Mitsunori
, p. 1973 - 1976 (2008)
A variety of 1-alkyl- and aryl-substituted indazolones were synthesized easily starting from commercially available 2-halobenzoic acids and hydrazines via the copper-catalyzed intramolecular C-N bond formation of 2-halobenzohydrazides under mild conditions.
