2-Methoxy-3-<4-nitro-2-benzoyl-phenoxy>-oestratrien-<1,3,5(10)> is a complex organic compound with a molecular structure that features a 17β-estradiol core, which is a naturally occurring hormone. This specific compound is characterized by the presence of a methoxy group at the 2-position, a nitro group at the 4-position of the benzoyl-phenoxy moiety, and a benzoyl group attached to the 2-position of the phenoxy ring. The compound's structure is further defined by the numbering of the carbon atoms in the oestratrien framework, with the 1,3,5(10) notation indicating the positions of the carbon atoms in the steroid nucleus. This chemical is of interest in the field of pharmaceuticals and endocrinology, potentially for its hormonal activity or as a research tool in studying the effects of estrogen-like compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 4999-72-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4999-72:
(6*4)+(5*9)+(4*9)+(3*9)+(2*7)+(1*2)=148
148 % 10 = 8
So 4999-72-8 is a valid CAS Registry Number.
