Check Digit Verification of cas no

The CAS Registry Mumber 117898-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,8,9 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117898-52:
(8*1)+(7*1)+(6*7)+(5*8)+(4*9)+(3*8)+(2*5)+(1*2)=169
169 % 10 = 9
So 117898-52-9 is a valid CAS Registry Number.

-

Paragraph 0115; 0117; 0124; 0126; 0131; 0133; 0138-0141, (2021/11/03)

The invention relates to the technical field of preparation of pharmaceutical active pharmaceutical chemicals, in particular to a preparation method of palace progesterone. To the preparation method, 17 α - hydroxyl progesterone is used as a substrate, and nucleophilic addition reaction is carried out in sequence. An epoxidation reaction, an open-loop addition reaction, an elimination reaction, an esterification reaction and a hydrolysis reaction are adopted to obtain the toecliptin progesterone, and a precious metal catalyst and a carcinogenic solvent are not used in the preparation process simultaneously. ≥ 91%.
