89327-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89327-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,2 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89327-17:
(7*8)+(6*9)+(5*3)+(4*2)+(3*7)+(2*1)+(1*7)=163
163 % 10 = 3
So 89327-17-3 is a valid CAS Registry Number.

DIRECTED STEROID CHLORINATION CATALYZED BY AN INO-PAIRED TEMPLATE
Breslow, Ronald,Heyer, Dennis
, p. 5039 - 5042 (2007/10/02)
3-α-Cholestanyltrimethylammonium cation is catalytically chlorinated by iodobenzenesulfonate anions with geometric control and catalytic turnover of the template anion.Steroid sulfates with cationic templates also show directed catalysis.
