Check Digit Verification of cas no

The CAS Registry Mumber 34523-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,5,2 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34523-28:
(7*3)+(6*4)+(5*5)+(4*2)+(3*3)+(2*2)+(1*8)=99
99 % 10 = 9
So 34523-28-9 is a valid CAS Registry Number.

Method for efficiently preparing sulfuryl fluorides compound by catalytic fluorination

-

Paragraph 0101; 0102; 0103; 0104, (2019/05/22)

The invention belongs to the technical field of the chemical synthesis, and particularly relates to a method for efficiently preparing a sulfuryl fluorides compound by catalytic fluorination. The provided method for efficiently preparing the sulfuryl fluorides compound by the catalytic fluorination comprises the following steps: enabling a sulfonyl chlorides compound to react with a hydroge fluoride under the action of a catalyst of a sulfonic acids derivative, to obtain the sulfuryl fluorides compound. A novel catalytic technology is provided, and the method has extensive substrate applicability. Efficient catalytic efficiency and yield are expressed.

A convenient, one-pot procedure for the preparation of acyl and sulfonyl fluorides using Cl3CCN, Ph3P, and TBAF(t -BuOH) 4

Kim, Joong-Gon,Jang, Doo Ok

experimental part, p. 3049 - 3052 (2011/02/25)

Various carboxylic acids were converted into acyl fluorides in excellent yields by treatment with trichloroacetonitrile, triphenylphosphine, and TBAF(t-BuOH)4 at room temperature. The reaction was applicable to the preparation of acid-sensitive amino acid fluorides without deprotection or rearrangement
