Check Digit Verification of cas no
The CAS Registry Mumber 18233-34-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,3 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18233-34:
(7*1)+(6*8)+(5*2)+(4*3)+(3*3)+(2*3)+(1*4)=96
96 % 10 = 6
So 18233-34-6 is a valid CAS Registry Number.

Paragraph 0062-0063; 0068; 0070-0073, (2020/01/12)
The invention discloses a recycling method of 1-phenyl-5-hydroxytetrazole, and belongs to the technical field of medicinal chemistry. The preparation method comprises the following steps: a byproduct1-phenyl-5-hydroxytetrazole generated in preparation process of a rosuvastatin calcium intermediate is converted into 1-phenyl-5-mercaptotetrazole; and meanwhile, the 1-phenyl-5-mercaptotetrazole is further used for preparing a rosuvastatin calcium intermediate or rosuvastatin calcium. According to the method disclosed by the invention, reasonable recycling of the byproduct 1-phenyl-5-hydroxytetrazole is realized, the raw materials are fully utilized, the production cost of rosuvastatin calcium and the intermediate thereof is reduced, and the emission of three wastes is reduced.
