18529-67-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18529-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,2 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18529-67:
(7*1)+(6*8)+(5*5)+(4*2)+(3*9)+(2*6)+(1*7)=134
134 % 10 = 4
So 18529-67-4 is a valid CAS Registry Number.

Microbiological Transformations Part 7. Microbiological Transformations of A-nor- and A-homo-5α-androstane derivatives with the fungus Cunninghamella elegans.

Crabb, Trevor A.,Ratcliffe, Norman M.

, p. 650 - 669 (2007/10/02)

The microbiological transformation of 17β-hydroxy-A-nor-5α-androstan-2-one, 17β-hydroxy-A-homo-5α-androstan-3-one and 5α-androstan-3,17-dione, by Cunninghamella elegans is dominated by 9α-hydroxylation whereas 17β-hydroxy-5α-androstan-3-one undergoes predominant 7α-monohydroxylation. 9α-Hydroxy-5α-androstane-3,17-dione and 9α-hydroxy-A-homo-5α-androstane-3,17-dione were synthesised by a sequence involving 11α-hydroxylation of the corresponding 3,17-diones by Aspergillus ochraceous.
