(24R)-Methylcholesta-3,5-diene and (24R)-Ethylcholesta-3,5-diene are two structurally similar organic compounds belonging to the family of steroids. Both compounds consist of a 27-carbon atom framework, with the difference being the presence of a methyl group (CH3) in the former and an ethyl group (C2H5) in the latter, both attached to the 24th carbon atom. These molecules feature a conjugated diene system, with double bonds at the 3rd and 5th positions, and a cyclohexane ring structure. They are important intermediates in the synthesis of various steroidal compounds, such as hormones and pharmaceuticals, and play a crucial role in the study of steroidal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 4970-37-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4970-37:
(6*4)+(5*9)+(4*7)+(3*0)+(2*3)+(1*7)=110
110 % 10 = 0
So 4970-37-0 is a valid CAS Registry Number.

Synthesis of (24R)-3β-hydroxystigmast-5-en-7-one

Kovganko,Kashkan

, p. 433 - 436 (2007/10/03)

The natural compound (24R)-3β-hydroxystigmast-5-en-7-one has been synthesized from β-sitosterol.

SYNTHESIS OF TRITERPENE AND STEROID GLYCOSIDES

Uvarova, Nina I.,Atopkina, Lyubov N.,Elyakov, Georgi B.

, p. 33 - 42 (2007/10/02)

The glycosylation of cholesterol, β-sitosterol, 28-O-acetylbetulin, and betulin with acylated glycosyl halides in the presence of Hg(OAc)2, Hg(CN)2, CdCO3, Ag2O, Ag2CO3, and HgO + HgBr2 usually gives acylated αβ-glycosides accompanied by acetates, ethers, and bromo and unsaturated derivatives of the initial alcohols.The use of Hg(CN)2 gave mainly β anomers (40-87percent), whereas α anomers preponderated when Hg(OAc)2 was the catalyst.When there was a deficiency of hydrogen halide acceptor and in the presence of the acidic catalyst HgBr2*HBr, the β anomer, produced initially, underwent anomerisation.Cholesteryl α-D-glucopyranoside tetra-acetate (48percent) was obtained by anomerisation of the β anomer.
