Check Digit Verification of cas no
The CAS Registry Mumber 71550-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71550-33:
(7*7)+(6*1)+(5*5)+(4*5)+(3*0)+(2*3)+(1*3)=109
109 % 10 = 9
So 71550-33-9 is a valid CAS Registry Number.

Paragraph 0033; 0034; 0035, (2016/12/01)
The invention discloses a method for preparing 16,17-dialkoxyviolanthrone derivatives. A readily available 16,17-dimethoxyviolanthrone dye is used as an initial raw material, a 16,17-dihydroxyviolanthrone intermediate is prepared through demethylation, and the corresponding 16,17-dialkoxyviolanthrone derivatives are synthesized through Williamson ether synthesis reaction. The method has the characteristics of short whole reaction route, high yield, mild reaction conditions and low cost.
