Check Digit Verification of cas no
The CAS Registry Mumber 91742-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,4 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91742-21:
(7*9)+(6*1)+(5*7)+(4*4)+(3*2)+(2*2)+(1*1)=131
131 % 10 = 1
So 91742-21-1 is a valid CAS Registry Number.

Paragraph 0056; 0057; 0060; 0061, (2019/06/12)
The invention provides a preparation method of a bis-trifluoro sulfonimide salt. The method comprises the following steps of S1, preparing corresponding N-alkyl-substituted bis-trifloromethane sulfonimide with primary amine and trifluoromethyl sulfonic anhydride; S2, reacting the N-alkyl-substituted bis-trifloromethane sulfonimide with a salt to obtain a crude product; S3, crystallizing the crudeproduct and then drying the crude product in vacuum to obtain the bis-trifloromethane sulfonimide salt. The method has the advantages that N-alkyl-substituted bis-trifloromethane sulfonimide is stablein property and does not generate corrosive substances in a whole reaction process, three wastes are hardly generated, the method is suitable for large-scale production, the high-purity battery-gradebis-trifloromethane sulfonimide salt can be obtained, and a high implementation value and considerable social and economic benefits are acquired.
