Check Digit Verification of cas no

The CAS Registry Mumber 77207-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,0 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77207-01:
(7*7)+(6*7)+(5*2)+(4*0)+(3*7)+(2*0)+(1*1)=123
123 % 10 = 3
So 77207-01-3 is a valid CAS Registry Number.

-

Paragraph 0063; 0069; 0070, (2016/10/27)

The invention relates to the field of herbicides and specifically discloses a preparation method of acifluorfen. The acifluorfen is a compound shown by formula (1) in the specification. The method comprises the following steps: (1) dropwise adding the compound shown by formula (2) in the specification into an organic solvent containing alkali carbonate and the compound shown by formula (3) in the specification so that the compound shown by formula (3) contacts and reacts with the compound shown by formula (2) to obtain the compound shown by formula (4); and (2) performing alkaline hydrolysis and acidification of the compound shown by formula (4) to obtain the compound shown by formula (1). By adopting the preparation method, the target compound can be prepared with relatively high yield in relatively mild reaction conditions.
