49643-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49643-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 49643-99:
(7*4)+(6*9)+(5*6)+(4*4)+(3*3)+(2*9)+(1*9)=164
164 % 10 = 4
So 49643-99-4 is a valid CAS Registry Number.

Microbiological Transformations. Part 4. Microbiological Transformations of 5α-Androstan-17-ones and of 17a-Aza-D-homo-5α-androstan-17-ones with the Fungus Cunninghamella elegans

Crabb, Trevor A.,Saul, John A.,Williams, Roger O.

, p. 1041 - 1045 (2007/10/02)

The microbiological transformation of 5α-androstan-17-one, and the 3β-acetoxy- and 3α-hydroxy-derivatives, by Cunninghamella elegans is dominated by 1β,7-dihydroxylation or 7-monohydroxylation. 3α-Acetoxy-5α-androstan-17-one undergoes predominant 6β,11β-dihydroxylation. 17a-Aza-D-homo-5α-androstan-17-one and the 3α-acetoxy-derivative undergo predominant monohydroxylation at 6β or 7α, in contrast to the 3β-acetoxy-derivative which, although undergoing similar monohydroxylation, gives good yield of 9α-monohydroxylated products.
