250340-58-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250340-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,3,4 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 250340-58:
(8*2)+(7*5)+(6*0)+(5*3)+(4*4)+(3*0)+(2*5)+(1*8)=100
100 % 10 = 0
So 250340-58-0 is a valid CAS Registry Number.

Synthesis of Substituted Dithia-9-crown-3-ethers
Romdhani, M.,Chaabouni, M. M.
, p. 3939 - 3948 (2007/10/03)
Diethylene glycol monochlorides were prepared from epoxides by action of the chloroethanol. Their conversion into substituted dithia-9-crown-3-ethers has been realized by treatment with p-toluenesulfonyl chloride, followed by the action of 1,2-dimercaptoe
