Δ⁴-Cholesten-3-one ethylene dithioacetal is a chemical compound derived from cholesterol, specifically a steroidal ketone with a Δ⁴ double bond and a 3-ketone functional group. It is characterized by the presence of an ethylene dithioacetal group, which is a sulfur-containing protecting group that can be used to shield the ketone functionality during chemical reactions. Δ⁴-Cholesten-3-one ethylene dithioacetal is often used in organic synthesis, particularly in the preparation of steroidal compounds and other complex organic molecules. The ethylene dithioacetal group can be selectively removed under mild conditions, making it a valuable tool for protecting ketones in multi-step synthesis processes.

Check Digit Verification of cas no

The CAS Registry Mumber 2791-51-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2791-51:
(6*2)+(5*7)+(4*9)+(3*1)+(2*5)+(1*1)=97
97 % 10 = 7
So 2791-51-7 is a valid CAS Registry Number.
