4127-28-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4127-28-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4127-28:
(6*4)+(5*1)+(4*2)+(3*7)+(2*2)+(1*8)=70
70 % 10 = 0
So 4127-28-0 is a valid CAS Registry Number.

Method for making alkanesulphonyl chlorides

-

Page 3, (2008/06/13)

In the process according to the invention for the manufacture of an alkanesulphonyl chloride RCH2—SO2Cl by oxidative chlorolysis of the corresponding mercaptan RCH2—SH, the mercaptan and water are introduced into the reaction mixture in the form of a dispersion of water in the mercaptan. This makes it possible to obtain both an alkanesulphonyl chloride of very good quality and a hydrochloric acid of commercial grade.
