Cholesta-1,3,7-trien, also known as 7-dehydrocholesterol or 7-dehydrocholestrol, is a naturally occurring steroid compound found in the skin. It is a key precursor in the synthesis of vitamin D3, which is essential for maintaining healthy bones and immune function. When the skin is exposed to ultraviolet B (UVB) radiation from sunlight, cholesta-1,3,7-trien undergoes a photochemical reaction, leading to the formation of previtamin D3. Cholesta-1,3,7-trien is then thermally isomerized to form the biologically active vitamin D3, which plays a crucial role in calcium homeostasis and overall health.

7443-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7443-20-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 7443-20:
(6*7)+(5*4)+(4*4)+(3*3)+(2*2)+(1*0)=91
91 % 10 = 1
So 7443-20-1 is a valid CAS Registry Number.
