Xanthosine, 2',3'-O-(1-methylethylidene)-, also known as 1-methylethylidene-protected xanthosine, is a chemical compound derived from xanthosine, a naturally occurring nucleoside. It is characterized by the presence of a 1-methylethylidene (also known as an isopropylidene) group, which is a three-carbon chain with a methyl group at one end and a double bond at the other. This modification is used to protect the 2' and 3' hydroxyl groups of the ribose sugar moiety in xanthosine, preventing unwanted reactions at these positions. The compound is often used in organic synthesis and as an intermediate in the preparation of various nucleoside analogs, which have potential applications in medicinal chemistry and drug development.

4137-57-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4137-57-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,3 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4137-57:
(6*4)+(5*1)+(4*3)+(3*7)+(2*5)+(1*7)=79
79 % 10 = 9
So 4137-57-9 is a valid CAS Registry Number.
