95846-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 95846-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,8,4 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 95846-28:
(7*9)+(6*5)+(5*8)+(4*4)+(3*6)+(2*2)+(1*8)=179
179 % 10 = 9
So 95846-28-9 is a valid CAS Registry Number.

The synthesis of the previously unknown 1-chloroestradiol (1), is reported.Addition of N-chlorosuccinimide/NaI in dioxane to 4-aminoestradiol 3-methyl ether (2), resulted in exclusive chlorination of the 1-position.Subsequent deamination and demethylation afforded 1 in good yields.
