3,17-Dioxo-19-methansulfonyloxy-Δ4-androsten is a complex organic compound with the molecular formula C21H30O5S. It is derived from the androstane steroid nucleus, specifically a Δ4-androsten, which is a type of androstane with a double bond between carbons 4 and 5. The compound features two ketone groups (oxo groups) at the 3 and 17 positions, and a methansulfonyloxy group at the 19 position. This group is a methanesulfonyl ether, which is a protecting group used in organic synthesis to protect hydroxyl groups. The compound is of interest in the field of organic chemistry, particularly in the synthesis of steroidal compounds and pharmaceuticals, due to its unique structure and potential applications in drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 5295-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,9 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5295-60:
(6*5)+(5*2)+(4*9)+(3*5)+(2*6)+(1*0)=103
103 % 10 = 3
So 5295-60-3 is a valid CAS Registry Number.
