37772-03-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37772-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,7 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 37772-03:
(7*3)+(6*7)+(5*7)+(4*7)+(3*2)+(2*0)+(1*3)=135
135 % 10 = 5
So 37772-03-5 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.
