Vitamin D2 trimethylsilyl ether is a chemical compound derived from vitamin D2, also known as ergocalciferol. It is characterized by the presence of a trimethylsilyl (TMS) group, which is a common protecting group in organic chemistry. The TMS group is added to the hydroxyl group of vitamin D2, forming an ether linkage. This modification is often used to protect the hydroxyl group from unwanted reactions, such as oxidation or dehydration, and can be removed under mild conditions when the protection is no longer needed. The compound is used in various applications, including pharmaceuticals and chemical research, to facilitate the synthesis of vitamin D2 derivatives or to study its chemical properties in a controlled manner.

Check Digit Verification of cas no

The CAS Registry Mumber 2754-48-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2754-48:
(6*2)+(5*7)+(4*5)+(3*4)+(2*4)+(1*8)=95
95 % 10 = 5
So 2754-48-5 is a valid CAS Registry Number.
