126800-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126800-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,8,0 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126800-39:
(8*1)+(7*2)+(6*6)+(5*8)+(4*0)+(3*0)+(2*3)+(1*9)=113
113 % 10 = 3
So 126800-39-3 is a valid CAS Registry Number.

Rearrangement of 1,3-Thiazolidine Sulfoxides
Mah, He Duck,Lee, Wha Suk
, p. 1447 - 1451 (2007/10/02)
Oxidation of 1,3-thiazolidines 3 gave a mixture of cis- and trans-sulfoxides 4 and 5, major and minor, respectively.In the presence of an acid catalyst both the cis and trans sulfoxides underwent ring expansion reaction to produce dihydro-1,4-thiazines 2
