40026-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40026-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,2 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40026-99:
(7*4)+(6*0)+(5*0)+(4*2)+(3*6)+(2*9)+(1*9)=81
81 % 10 = 1
So 40026-99-1 is a valid CAS Registry Number.

Dibenzodioxadithiasilonin: Synthesis and Characterization
Pastor, Stephen D.,Denney, Dorothy Z.
, p. 681 - 683 (2007/10/02)
The reaction of 2,4-di-t-butylphenol, 4, with sulfur monochloride gave the trithiobisphenol 5 rather than the expected dithiobisphenol 7.The thiol 6 was obtained by the reduction of 5 with zinc under acidic conditions.The dithiobisphenol 7 was prepared by
