618457-34-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 618457-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,4,5 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 618457-34:
(8*6)+(7*1)+(6*8)+(5*4)+(4*5)+(3*7)+(2*3)+(1*4)=174
174 % 10 = 4
So 618457-34-4 is a valid CAS Registry Number.

Stereoselective halogenation of the 16-hydroxymethyl-3-methoxy-13α-estra-1,3,5(10)-trien-17-ols and their solvolytic investigation

Woelfling, Janos,Mernyak, Erzsebet,Forgo, Peter,Schneider, Gyula

, p. 451 - 458 (2007/10/03)

The primary hydroxy functions of 16α-hydroxymethyl-3-methoxy-13α-estra-1,3,5(10)-trien-17β-ol (3a) and 16β-hydroxymethyl-3-methoxy-13α-estra-1,3,5(10)-trien-17α-ol (4a) were stereoselectively transformed into good leaving groups. On alkaline methanolysis of the 16-halomethyl or 16-tolylsulfonyloxymethyl derivatives, a new D-seco-13α-estrone derivative was obtained in high yield.
