Check Digit Verification of cas no
The CAS Registry Mumber 81-26-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81-26:
(4*8)+(3*1)+(2*2)+(1*6)=45
45 % 10 = 5
So 81-26-5 is a valid CAS Registry Number.

The invention discloses a method for synthesizing a Vat Golden Grange G original dye, which includes the specific steps of: (1) a bromination reaction: taking 2-methyl anthraquinone as a raw material, taking an aprotic solvent as a medium, and reacting with a liquid bromine in a weak base environment to generate 1-bromo-2-methyl anthraquinone; (2) a coupling reaction: taking the 1-bromo-2-methyl anthraquinone as the raw material, adding a catalyst, taking the aprotic solvent as the medium, and producing biquinone C through the coupling reaction; and (C) a closed loop oxidation reaction: taking the biquinone C as the raw material, performing the closed loop reaction in a stable solvent formed by a strong base and an alcoholic solvent, and obtaining the Vat Golden Grange G original dye through an air oxidation reaction. In this technology route, by-products are few, the environmental pollution is little, the reaction yield is higher, the reaction time is shorter, and the industrial production is more convenient.
