67089-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67089-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,8 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67089-87:
(7*6)+(6*7)+(5*0)+(4*8)+(3*9)+(2*8)+(1*7)=166
166 % 10 = 6
So 67089-87-6 is a valid CAS Registry Number.

ASYMMETRIC INDUCTION TO SULFUR ATOM: STEREOCONTROLLED S-OXIDATION OF THIAZOLIDINES
Ando, Wataru,Huang, Liren
, p. 3391 - 3394 (2007/10/02)
Oxidation of (2R,4R)-2,4-disubstituted thiazolidines with m-CPBA affords the trans sulfoxide exclusively.Oxidation of (2R,4R)-4-hydroxymethyl thiazolidines with Ti(OiPr)4/TBHP, however, favors to give the cis sulfoxide.
