Check Digit Verification of cas no
The CAS Registry Mumber 3089-17-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3089-17:
(6*3)+(5*0)+(4*8)+(3*9)+(2*1)+(1*7)=86
86 % 10 = 6
So 3089-17-6 is a valid CAS Registry Number.

Preparation method for quinacridone and derivatives of quinacridone
-
Paragraph 0037, (2017/08/29)
The invention relates to the field of synthesis of organic pigments and discloses a preparation method for quinacridone and derivatives of the quinacridone. The preparation method comprises the steps that dimethyl succinate generates sodium dimethyl succinylsuccinate (DMSS) through cyclic condensation under an effect of sodium methoxide, and then being acidized into DMSS; condensation reaction occurs between the DMSS and aniline or substituted aniline, an intermediate product generated during condensation is directly oxidized and dehydrogenated by sodium 3-nitrobenzene sulfonate to obtain an oxidative product; and finally coarse products of the quinacridone or the derivatives of the quinacridone are prepared from the oxidative product in a ring-closing mode under an effect of polyphosphoric acid, and finally finished products of the quinacridone or the derivatives of the quinacridone are obtained through pigmentation treatment.
