145458-99-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 145458-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,4,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145458-99:
(8*1)+(7*4)+(6*5)+(5*4)+(4*5)+(3*8)+(2*9)+(1*9)=157
157 % 10 = 7
So 145458-99-7 is a valid CAS Registry Number.

Antihormonal properties of some new A-homo-B, 19-dinor steroids of the androstane series

Kasal, Alexander,Hampl, Richard,Bicikova, Marie,Starka, Luboslav

, p. 460 - 463 (2007/10/02)

On solvolysis of Westphalen-type steroids with a leaving group in the position 6β (e.g., 2), products of elimination (followed by rearrangement and fragmentation of the steroid skeleton) were prepared (e.g., 4 and 5).These products were subsequently converted to suitable analogs of the compound, which has been reported to promote hair growth (1).Compounds 11 to 13 exhibited strong antiandrogenic activity in vivo; however, this activity could not be interpreted either in terms of inhibition of 5α-reductase or by strong binding to an androgen receptor.Keywords: steroids with modified skeleton; androgen receptors; antiandrogens; 5α-reductase inhibitor; testosterone; dihydotestosterone
