Check Digit Verification of cas no
The CAS Registry Mumber 680-05-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 680-05:
(5*6)+(4*8)+(3*0)+(2*0)+(1*5)=67
67 % 10 = 7
So 680-05-7 is a valid CAS Registry Number.

Paragraph 0085; 0089-0091; 0096; 0100-0102, (2021/03/05)
The invention discloses a synthesis method of heptafluoroisobutyronitrile, which comprises the following steps: (1) reacting hexafluoropropylene with carbon dioxide under the catalysis of fluoride salt to obtain heptafluoroisobutyrate; (2) acidifying the obtained heptafluoroisobutyric acid, and then carrying out esterification reaction with alcohol to obtain heptafluoroisobutyrate; and (3) reacting the obtained heptafluoroisobutyrate with ammonia, and dehydrating to obtain heptafluoroisobutyronitrile. The synthesis method has the advantages of easily available raw materials, mild reaction conditions, high reaction conversion rate and yield, easy separation and purification, simple and safe process operation, short synthesis route and low cost.
