78806-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78806-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,0 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78806-45:
(7*7)+(6*8)+(5*8)+(4*0)+(3*6)+(2*4)+(1*5)=168
168 % 10 = 8
So 78806-45-8 is a valid CAS Registry Number.

CONVERSION OF 15α-HYDROXY-11-OXO-PROGESTERONE TO 3β,11α,15β-TRIHYDROXY-5-PREGNEN-20-ONE
Weihe, Gary R.,McMorris, Trevor C.
, p. 291 - 302 (2007/10/02)
3β,11α,15β-Trihydroxy-5-pregnen-20-one, an intermediate required for the synthesis of the oogoniols, has been prepared from 15α-hydroxy-11-oxo-progesterone in an overall yield of 16percent.The three isomers (at C-11, C-15) of the pregnene were also prepared.
