2135-57-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2135-57-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2135-57:
(6*2)+(5*1)+(4*3)+(3*5)+(2*5)+(1*7)=61
61 % 10 = 1
So 2135-57-1 is a valid CAS Registry Number.

Biosynthesis of Estrogens bz Microsomal Placental Aromatase; Isolation and Metabolism of 10β-Hydroxyestr-4-ene-3,17-dione

Caspi, Eliahu,Dharmaratne, H. Ranjith W.,Shackleton, Cedric

, p. 1699 - 1700 (1989)

Incubation of -19-oxoandrost-4-ene-3,17-dione (2a) with microsomal aromatase gave inter alia -10β-hydroxyestr-4-ene-3,17-dione (1), whose analogue (1b) on incubation with the aromatase gave 10β,17β-dihydroxyestr-4-en-3-one (1d) (ca. 10percent) and no estrogens which would indicate that (1b) is not an obligatory estrogen precursor.
