Check Digit Verification of cas no
The CAS Registry Mumber 77804-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,0 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77804-81:
(7*7)+(6*7)+(5*8)+(4*0)+(3*4)+(2*8)+(1*1)=160
160 % 10 = 0
So 77804-81-0 is a valid CAS Registry Number.

Preparation method of C.I. pigment yellow 180
-
Paragraph 0076; 0077; 0078; 0079; 0084, (2016/10/10)
The invention provides a preparation method of C.I. pigment yellow 180. The preparation method comprises the following steps: compounding three pigments in the synthetic process, carrying out diazotization by three-stage diazo, carrying out beating on 5-glycylacetylbenzimidazolone and carrying out high-pressure homogenization, and controlling pH value with trisodium phosphate so as to finally prepare the C.I. pigment yellow 180. The product has advantages of uniform particle size, soft particle, good light resistance and resistance transference, high tinting strength and excellent light resistance, heat resistance, solvent resistance, acid resistance and alkali resistance and processing application performance.
