641-80-5 Usage

Definition

ChEBI: A C21-steroid that is pregnane which contains a double bond between positions 5 and 6 and is substituted by oxo groups at positions 3 and 20 as well as a hydroxy group at position 17.

Check Digit Verification of cas no

The CAS Registry Mumber 641-80-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 641-80:
(5*6)+(4*4)+(3*1)+(2*8)+(1*0)=65
65 % 10 = 5
So 641-80-5 is a valid CAS Registry Number.

Synthesis of [3α-3H] 17α-Hydroxy pregnenolone and [3α-3H] Pregnenolone

Tian, Yuan,Hong, Yang,Bonacorsi, Samuel J.,Balog, Aaron,Gong, Sharon

, p. 1 - 11 (2014/02/14)

For the first time, [3α-3H] 17α-hydroxy pregnenolone (1) was synthesized through a multiple step sequence. The presence of [3β-3H] isomer in RP-HPLC purified product was identified by tritium NMR. The [3β-3H] isomer was then separated from [3α-3H] 17α-hydroxy pregnenolone with chiralPAK AD-H column. [3α-3H] pregnenolone (2) was synthesized from commercial available 5-pregnen-3,20-dione in one step with an improved procedure. [3α-3H] 17α-hydroxy pregnenolone (1) was synthesized through a multiple step sequence. The presence of [3β- 3H] isomer was identified then separated with chiralPAK AD-H column. [3α-3H] pregnenolone (2) was synthesized from commercial available 5-pregnen-3,20-dione in one step. Copyright
