104143-54-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104143-54-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,1,4 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 104143-54:
(8*1)+(7*0)+(6*4)+(5*1)+(4*4)+(3*3)+(2*5)+(1*4)=76
76 % 10 = 6
So 104143-54-6 is a valid CAS Registry Number.

REACTIONS OF CYCLIC DISULFIDES WITH CARBENES; DESULFURIZATION AND INSERTION
Ando, Wataru,Kumamoto, Yorio,Takata, Toshikazu
, p. 5187 - 5190 (2007/10/02)
Reactions of several cyclic disulfides with carbenes generated by catalytic and photochemical decompositions of diazo compounds have been studied.Carbenes reacted with cyclic disulfides yielding 1,3-dithiane quantitatively as S-S insertion reaction, while
