Check Digit Verification of cas no

The CAS Registry Mumber 89522-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,2 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89522-39:
(7*8)+(6*9)+(5*5)+(4*2)+(3*2)+(2*3)+(1*9)=164
164 % 10 = 4
So 89522-39-4 is a valid CAS Registry Number.

Synthesis of Some 4-Substituted-2-(o-halogenophenyl)-1,2,3-triazoles

Swartz, David L.,Karash, Angela R.,Berry, Laura A.,Jaeger, David L.

, p. 1561 - 1564 (2007/10/02)

Mesoladehyde 1,3-dioxime was treated with either 2,4,6-trichlorophenyl- (a), o-fluorophenyl- (b), or o-bromophenyl- (c) hydrazine to give corresponding mesoaldehyde 1,3-dioxime-2-halogenophenylhydrazones (1a,b,c).The latter were O-acetylated with acetic anhydride, and cyclized to triazole 4-oximes (3b,c) or triazole 4-O-acetyloximes (6a,b,c) with cesium carbonate, then converted to nitrile (7a,b,c) by refluxing with acetic anhydride followed by pyrolysis, or to aldehydes (4a,b,c) by hydrolysis.The nitriles (7a,b,c) were also converted to acids (9a,b,c), esters (10a,b,c), amides (8a,c), an alcohol (11a), and an amine (12a).In addition , tetrazoles of two types were prepared.The first (13d,e) were obtained from the acid chlorides by the action of 5-aminotetrazole, whereas the second (14f) was produced from the respective nitrile by the action of ammonium azide.
