Check Digit Verification of cas no
The CAS Registry Mumber 72205-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,0 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 72205-58:
(7*7)+(6*2)+(5*2)+(4*0)+(3*5)+(2*5)+(1*8)=104
104 % 10 = 4
So 72205-58-4 is a valid CAS Registry Number.

Stereochemistry of hydrogen loss during C-21 dehydroxylation of tetrahydrodeoxycorticosterone by Eubacterium lentum
Holland, Herbert L.,Ninniss, Ronald W.,Brown, Frances M.
, p. 1590 - 1595 (2007/10/02)
The loss of hydrogen from the C-21 position of 5β-pregnane-3α,21-diol-20-one (tetrahydrodeoxycorticosterone, THDOC) during reductive removal of the 21-hydroxy group by the anaerobic bacterium Eubacterium lentum has been shown to be selective for the pro-S position by the use of THDOC labelled with deuterium at the C-21 pro-S and C-21 pro-R positions.The labelled substrates were obtained by using the bacterium Clostridium paraputrificum to reduce chemically prepared C-21 labelled samples of pregn-4-en-21-ol-3,20-dione (deoxycorticosterone, DOC) at C-3 and C-4 (5).The stereochemistry of deuterium label introduced by chemical means at C-21 of DOC was determined by comparison with a sample of 21-(R)-DOC-21-d1 produced by reduction of the corresponding aldehyde pregn-4-en-21-al-3,20-dione, 21-d by the enzyme 21-hydroxysteroid NAD oxidoreductase from beef liver. Key words: Eubacterium, Clostridium, steroids, tetrahydrodeoxycorticosteroids.
The mechanism of enzymic hydroxyl group removal from C-21 of tetrahydrodeoxycorticosterone
Holland, Herbert L.,Riemland, Elly
, p. 981 - 983 (2007/10/02)
The C-21 hydroxyl group of C-17- and C-21-deuterium labelled tetrahydrodeoxycorticosterone is removed by the anaerobic intestinal bacterium Eubacterium lentum ATCC 25559 with retention of deuterium label at C-17α and loss of one of the two deuterium atoms originally present at C-21.Dehydroxylation at C-21 proceeds with an apparent primary kinetic isotope effect, KH/KD at C-21 of 2.6.These data suggest a route for C-21 dehydroxylation involving a C-20(21)-enediol intermediate.
