Check Digit Verification of cas no
The CAS Registry Mumber 1552-42-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1552-42:
(6*1)+(5*5)+(4*5)+(3*2)+(2*4)+(1*2)=67
67 % 10 = 7
So 1552-42-7 is a valid CAS Registry Number.

Paragraph 0017; 0018, (2017/08/23)
Crystal violet lactone synthesis method, relates to a method for synthesizing the thermo-compression is sensitive dye, in order to urea, dimethyl aniline, inter-a aminobenzoic acid, P-dimethyl amino formaldehyde and other material as the raw material for synthesis, through the Schiff base stage, urea intermediate stage, colorless crystalviolet stage and the last stage of the oxidation reaction, synthetic crystal violet lactone. Synthetic method comprises the stage of: (1) Schiff base stage: to di-methyl amino formaldehyde and urea reaction generating Schiff base; (2) urea intermediate stage: a stage on the production of products and dimethyl aniline reaction to obtain the urea intermediate; (3) colorless crystal violet lactone stage: urea intermediate and inter-dimethylamino benzoic acid as a raw material reacts to produce a colourless crystalviolet; (4) oxidation reaction stage: colorless crystalline purple after hydrogen peroxide generating crystal violet lactone catalytic oxidation. The method to avoid impurity generated synthetic method, thereby improving the yield of the product, at the same time reduces the discharge of solid wastes. (by machine translation)
