974-76-5 Usage

Uses

Used in Pharmaceutical Industry:
(17beta)-17-(chloroethynyl)-3-methoxyestra-1,3,5(10)-trien-17-ol is used as a selective estrogen receptor modulator (SERM) for its potential role in treating hormone-related conditions. Its unique chloroethynyl group endows it with distinct properties that may offer therapeutic benefits in managing diseases like breast cancer and osteoporosis.
Further research is essential to elucidate the compound's mechanism of action and to assess its safety and efficacy profile fully. This will pave the way for its potential integration into clinical practice and the development of novel treatment strategies for patients suffering from hormone-related disorders.

Check Digit Verification of cas no

The CAS Registry Mumber 974-76-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,7 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 974-76:
(5*9)+(4*7)+(3*4)+(2*7)+(1*6)=105
105 % 10 = 5
So 974-76-5 is a valid CAS Registry Number.
