3β-(toluene-4-sulfonyloxy)-pregna-5,16-dien-20-one is a complex organic compound belonging to the steroid family, specifically a derivative of pregnane. It features a pregnane core with a 5,16-dien structure, indicating the presence of two double bonds at the 5th and 16th carbon positions. The 3β position is substituted with a toluene-4-sulfonyloxy group, which is a toluene molecule with a sulfonyl group attached to the 4th carbon and an oxygen atom bonded to the 3rd carbon of the pregnane structure. This chemical is known for its potential applications in pharmaceuticals, particularly in the synthesis of corticosteroids, due to its structural similarity to natural steroid hormones. The compound's specific functional groups and stereochemistry make it a valuable intermediate in the development of drugs targeting various medical conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 6996-36-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6996-36:
(6*6)+(5*9)+(4*9)+(3*6)+(2*3)+(1*6)=147
147 % 10 = 7
So 6996-36-7 is a valid CAS Registry Number.
