19-Ketoprogesterone is a naturally occurring steroid hormone that plays a significant role in the human body. It is a metabolite of progesterone, a hormone essential for maintaining pregnancy and regulating the menstrual cycle. Derived from cholesterol, 19-ketoprogesterone is involved in the synthesis of other important hormones, such as cortisol and aldosterone. 19-ketoprogesterone is also used as a marker for evaluating adrenal function and diagnosing certain medical conditions, like congenital adrenal hyperplasia. In summary, 19-ketoprogesterone is a crucial intermediate in hormone metabolism, with implications for reproductive health and adrenal gland function.

Check Digit Verification of cas no

The CAS Registry Mumber 974-38-9 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, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 974-38:
(5*9)+(4*7)+(3*4)+(2*3)+(1*8)=99
99 % 10 = 9
So 974-38-9 is a valid CAS Registry Number.
