601-90-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 601-90-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 601-90:
(5*6)+(4*0)+(3*1)+(2*9)+(1*0)=51
51 % 10 = 1
So 601-90-1 is a valid CAS Registry Number.

Novel metabolites of dehydroepiandrosterone and progesterone obtained in Didymosphearia igniaria KCH 6670 culture

Janeczko, Tomasz,Swizdor, Alina,Dmochowska-Gladysz, Jadwiga,Bialonska, Agata,Ciunik, Zbigniew,Kostrzewa-Suslow, Edyta

experimental part, p. 24 - 31 (2012/10/08)

Dehydroepiandrosterone (DHEA) (10) and its five derivatives: testosterone (1), androstenedione (2), 17α-methyltestosterone (6), progesterone (13) and pregnenolone (14) were subjected to microbial transformation by the filamentous fungus Didymosphaeria igniaria KCH 6670. The predominant metabolism of the incubated 5-ene steroids (10 and 14) occurred through 3β-hydroxy-steroid dehydrogenase/5,4-en isomerase pathways resulting in the generation of a 4-en-3-oxo system on ring-A. The transformations of C 19 steroids (1, 2, and 10) included a hydroxylation at 7α position, ketone-alcohol interconversion at C-17 and reduction of the double bond at C-4 and 3-keto group to the 3β-alcohol with 5α- stereochemistry at A/B ring. D. igniaria also carried out 6(7)-dehydrogenation and 6,7β-epoxidation during transformation of DHEA. Under these conditions transformation of DHEA (10) gave four products: 7α-hydroxyandrost-4-en-3, 17-dione (4), 17β-hydroxyandrost-4,6-dien-3-one (11), 17β- hydroxyandrost-6β-epoxy-4-en-3-one (12) and 3β,17β-dihydroxy- 5α-androstane (5). The compounds 11 and 12 are identified as DHEA metabolites for the first time. The transformation of C21 steroids (13 and 14) led to the mixture of mono- (mainly 11α- and 15β-) and dihydroxy- (7α,15β-; 14α,15β-; 11α,15β-; 11α,14α-) products. 7α,15β-Dihydroxypregnan-4-en-3,20- dione (18) and 14α,15β-dihydroxypregnan-4-en-3,20-dione (19) were found to be new compounds. The main product of transformation of 17α-methyltestosterone (6) was 12β-hydroxy-17α- methyltestosterone (7). The results of these transformations demonstrate the dependence of hydroxylation position on the structure of steroid nucleus.
