188949-02-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188949-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,4 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 188949-02:
(8*1)+(7*8)+(6*8)+(5*9)+(4*4)+(3*9)+(2*0)+(1*2)=202
202 % 10 = 2
So 188949-02-2 is a valid CAS Registry Number.

Modified Julia olefination and α aminoxylation reactions mediated convergent synthesis of 1α, 24 (R)-dihydroxyvitamin D3 (tacalcitol)

Martínez, Andrea,Santalla, Hugo,Garrido, Fátima,Gómez, Generosa,Fall, Yagamare

, p. 3568 - 3570 (2017)

A convergent synthesis of tacalcitol has been achieved starting from inexpensive and commercially available isovaleraldehyde and easily available Inhoffen-Lythgoe diol. Key steps include a proline catalyzed α aminoxylation and a Julia-Kocienski olefination.

An efficient stereoselective synthesis of 1α,24(R)-dihydroxyvitamin D3 by the dienyne route

Fall, Yagamare,Torneiro, Mercedes,Castedo, Luis,Mourino, Antonio

, p. 4703 - 4714 (2007/10/03)

1α,24(R)-Dihydroxyvitamin D3 (5e) was synthesized. The key step in the preparation of the side-chain was opening of the chiral epoxide 10 by the α-anion of the nitrile 9. The triene system was synthesized by the dienyne route.
