Check Digit Verification of cas no

The CAS Registry Mumber 475-71-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 475-71:
(5*4)+(4*7)+(3*5)+(2*7)+(1*1)=78
78 % 10 = 8
So 475-71-8 is a valid CAS Registry Number.

New flavanthrone synthesis method

-

Paragraph 0007, (2016/10/31)

The present invention discloses a new flavanthrone synthesis method belonging to the technical field of dye processing. The method is improved on the basis of a traditional process, and comprises six steps, in a condensation step, low-boiling dimethyl formamide is used, and recovery cost is reduced; an anhydrous ferric chloride and copper powder compound catalyst is used to improve reaction efficiency, and in addition, sodium chlorate and hydrochloric acid are used for removing copper, copper removing effect is good, and product competitiveness is enhanced.
