67889-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67889-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67889-33:
(7*6)+(6*7)+(5*8)+(4*8)+(3*9)+(2*3)+(1*3)=192
192 % 10 = 2
So 67889-33-2 is a valid CAS Registry Number.

INTERMEDIATES IN SPIROSULFURANE FORMATIONS
Kapovits, Istvan
, p. 39 - 59 (2007/10/02)
Spirosulfuranes can generally be prepared from the corresponding sulfides with halogenating agents or from sulfoxides by intramolecular dehydration.Mechanisms for the formations have been suggested and determined earlier (1979).Recently, intermediates in
