Check Digit Verification of cas no
The CAS Registry Mumber 6975-76-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,7 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6975-76:
(6*6)+(5*9)+(4*7)+(3*5)+(2*7)+(1*6)=144
144 % 10 = 4
So 6975-76-4 is a valid CAS Registry Number.

Pyridazine derivatives and related compounds. 23*. synthesis of 3-substituted pyrazolo[3,4-c] pyridazines and their application as disperse dyes
Deeb,Yassin,Ouf,Shehta
experimental part, p. 212 - 222 (2011/08/21)
Acetylacetone and malononitrile were coupled with diazotized arylamines to give arylazoacetylacetones and arylazomalononitriles. When refluxed with 3-hydrazino-4,5-diphenyl-1H-pyrazolo-[3,4-c]pyridazine in the presence of ethanol/HCl, they yielded the corresponding 3-[4-(arylazo)-3,5-dimethylpyrazol- 1-yl]- and 3-[3,5-diamino-4-(arylazo)pyrazol-1-yl]-4,5-diphenyl-1H-pyrazolo[3,4- c]pyridazine dyes. The dyes were applied to polyester and polyamide fabrics, and their spectral and fastness properties were measured.
