Check Digit Verification of cas no

The CAS Registry Mumber 18269-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,6 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18269-57:
(7*1)+(6*8)+(5*2)+(4*6)+(3*9)+(2*5)+(1*7)=133
133 % 10 = 3
So 18269-57-3 is a valid CAS Registry Number.

Reaction Products and Process of 2-Chloroethyl Ethyl Sulfide in Microemulsion Media

Mei-Ling, Lei,Hai-Ling, Xi,Ming, Shen,Ling, Yuan,Shi-Tong, Han

, p. 387 - 393 (2014/03/21)

The reaction of 2-chloroethyl ethyl sulfide was investigated in several oil-in-water microemulsions. The reaction products were identified by GC/MS, NMR, and LC/MS, and the reaction process was monitored by measuring peak height of reaction products and 2-chloroethyl ethyl sulfide with time by 1H NMR spectroscopy. The result showed that 2-chloroethyl ethyl sulfide degraded to 2-hydroxyethyl ethyl sulfide, cyclic sulfonium ion, open chain sulfonium chloro ion and sulfonium hydroxyl ion, and the reaction proceeded via a cyclic sulfonium ion intermediate. Based on the NMR results, a pseudoternary model was established for the reaction process of 2-chloroethyl ethyl sulfide in microemulsion.
