Check Digit Verification of cas no
The CAS Registry Mumber 446-57-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 446-57:
(5*4)+(4*4)+(3*6)+(2*5)+(1*7)=71
71 % 10 = 1
So 446-57-1 is a valid CAS Registry Number.

Dibenzo seven-membered ring derivative as well as preparation method and application thereof
-
Paragraph 0072; 0093-0094; 0099-0108, (2021/03/31)
The invention relates to a dibenzo seven-membered ring derivative as well as a preparation method and application thereof. The chemical structure of the dibenzo seven-membered ring derivative is shownas a formula (I), and X1 and X2 are respectively and independently selected from H, F, Cl, Br or I. The preparation method has easily available raw materials, and can ensure continuous supply and production; the raw materials are cheap and have the cost advantage; and thiophenol or sodium thiophenol is not used, so that the method is more environment-friendly and is also beneficial to the body health of related personnel. 7,8-difluorodibenzo[b,e]thiazepine-11(6H)-one as one of the products can further react to obtain 7,8-difluoro-6,11-dihydrobenzo[c][1]benzothiepin-11-ol, and the 7,8-difluoro-6,11-dihydrobenzo[c][1]benzothiepin-11-ol can be used as an important intermediate for preparing a drug baloxavir, so that baloxavir preparation cost is reduced.
