2550-89-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2550-89-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2550-89:
(6*2)+(5*5)+(4*5)+(3*0)+(2*8)+(1*9)=82
82 % 10 = 2
So 2550-89-2 is a valid CAS Registry Number.

3β-Hydroxy-5β-cholest-7-en-6-one as an Intermediate of 20-Hydroxyecdysone Biosynthesis in a Hairy Root Culture of Ajuga reptans var. atropurpurea

Nagakari, Mitsuhiro,Kushiro, Tetsuo,Yagi, Tomoko,Tanaka, Nobukazu,Matsumoto, Takeshi,et al.

, p. 1761 - 1762 (1994)

-, - and -Cholesterols and - and -3β-hydroxy-5β-cholest-7-en-6-ones were converted with a hairy root culture of Ajuga reptans var. atropurpurea into 20-hydroxyecdysone, in which the deuterium atoms retained their original positions, thus strongly suggesting that 3β-hydroxy-5β-cholest-7-en-6-one is an obligatory intermediate in the biosynthesis of ecdysteroids in the plant.

Synthesis of potential inhibitors of the biosynthesis of ecdysone, the moulting hormone of insects

Guilherme-Dolle, V.,Hetru, C.,Luu, B.

, p. 733 - 739 (2007/10/02)

We have synthesized new potential acetylenic inhibitors of the last step in the biosynthesis of ecdysone, the moulting hormone of insects.The key step in our synthesis is the introduction of the A/B cis ring junction (5β-H configuration) by regio- and stereoselective hydroboration of the Δ5 double bond (B-ring) of 7-dehydrocholesterol. - Keywords: ecdysteroid / ecdysteroid inhibitors / hydroboration / acetylenic derivatives
